Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	(1) Basis of Presentation The condensed consolidated financial statements included herein have been prepared by Giga-tronics Incorporated (the “Company”), pursuant to the rules and regulations of the Securities and Exchange Commission. The consolidated results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. In the opinion of management, the information contained herein reflects all adjustments (consisting of normal recurring entries) necessary to make the consolidated results of operations for the interim periods a fair statement of such operations. For further information, refer to the consolidated financial statements and footnotes thereto, included in the Annual Report on Form 10-K, filed with the Securities and Exchange Commission for the year ended March 30, 2013. The Company has incurred net losses of $681,000 in the first quarter of fiscal 2014, $4.2 million in fiscal year 2013, and $5.9 million in fiscal year 2012. These net losses have contributed to an accumulated deficit of $15.0 million at June 29, 2013, and elevate a cause for concern regarding the Company’s future. To address this concern Management has taken several actions to provide additional working capital over the current fiscal year, and reduce the costs and expenses going forward. On March 18, 2013 the Company entered into an Asset Purchase agreement with Teradyne Inc. (“Teradyne”), whereby Teradyne agreed to purchase the Giga-tronics Division product line known as SCPM for $1.0 million. The $1.0 million for SCPM is payable over the first nine months of fiscal 2014 (see Note 4, Gain on Sale of Product Line). To ensure the Company has the ability to continue borrowing over the next two fiscal years, on June 11, 2013 the Company extended its line of credit from October 12, 2012 to April 15, 2015, and increased the maximum advances associated with the Company’s accounts receivable from $2.0 million to $3.0 million (see Note 11, Line of Credit). To provide additional working capital for operations, on July 8, 2013 the Company received $858,000 in cash proceeds from Alara Capital AVI II, LLC, a Delaware limited liability company (the “Investor”). Under a Securities Purchase Agreement (“SPA”), the Company sold to the Investor 5,111.86 shares of a new Series D Convertible Voting Perpetual Preferred Stock and warrants to purchase up to 511,186 additional shares of common stock at the price of $1.43 per share. (see Note 13, Subsequent Event). To assist with the upfront purchases of inventory required for future product deliveries, the Company has entered into advance payment arrangements with a large customer, whereby the customer reimburses the Company for raw material purchases prior to the shipment of the finished products. In fiscal 2013 these advance payments totaled approximately $2.3 million. In fiscal 2014 the Company has currently contracted approximately $1.3 million of advance payments, and will seek similar terms with future agreements with the Customer, and other customers. On May 31, 2013 the Company completed the consolidation of its Santa Rosa, California facility into its headquarters in San Ramon, California. The Company expects to save approximately $500,000 annually in facility costs, and the Company expects other operational efficiencies associated with having the majority of the company at one location. Management also plans to further increase operational efficiencies by continuing to work down product inventories that are on hand at June 29, 2013, and paid for. In addition, Management will continue to review all aspects of the business in an effort to reduce costs and expenses, while continuing to invest in new product development for future revenue streams. Management believes that through these efforts the Company will have the working capital required to continue its operations through fiscal 2014. Fiscal Year The Company’s financial reporting year consists of either a 52 week or 53 week period ending on the last Saturday of the month of March. Fiscal year 2014, ending on March 29, 2014, and fiscal year 2013, which ended on March 30, 2013, contained 52 weeks. Quarterly periods within each such fiscal year are in most cases 13 weeks rather than three calendar months. All references to three month period and years in the consolidated financial statements relate to fiscal periods or years rather than three month calendar quarters or calendar years. Certain prior period amounts have been reclassified to conform to the current period’s presentation. Adoption of New Accounting Standards In July, 2013, the FASB issued Accounting Standards Update 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” U.S. GAAP does not include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments in this ASU state that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This standard applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The effect of adopting this standard had no effect on the Company’s operating results or financial condition.
