             Giga-tronics Reports Fourth Quarter and FY 2004 Results

      SAN RAMON, CA - Giga-tronics Incorporated (NASDAQ/NMS: GIGA) reported
today that the net loss in the fourth quarter of fiscal year 2004 decreased 28%
to $1,712,000 or $0.36 per fully diluted share compared to $2,387,000 or $0.51
per fully diluted share for the fourth quarter of last year. For the fiscal year
ended March 27, 2004, the net loss decreased 37% to $6,821,000 or $1.45 per
share fully diluted versus $10,762,000 or $2.31 per fully diluted share for the
same period a year ago.

      Loss from continuing operations for the fourth quarter was $1,727,000 or
$0.37 per fully diluted share compared to a loss from continuing operations of
$1,101,000 or $0.24 per fully diluted share for the same period a year ago.
Giga-tronics elected to discontinue the operations at its Dymatix division
during the first quarter of FY2004.

      For the 2004 fiscal year, the net loss from continuing operations was
$4,444,000 or $0.94 per fully diluted share versus a net loss from continuing
operations of $8,426,000 or $1.81 per fully diluted share last year. Net sales
from continuing operations were $3,295,000 in the fourth quarter of fiscal 2004
versus $4,730,000 in the fourth quarter of fiscal 2003. Net sales for fiscal
year 2004 decreased 16% from the prior year to $17,491,000 from $20,822,000.

      New orders from continuing operations have increased over the last three
quarters. Orders from continuing operations increased 61% in the fourth quarter
of FY 2004 from the same quarter a year ago. Our book-to-bill ratio in the
fourth quarter of fiscal 2004 was 1.58 compared to 0.68 in the fourth quarter of
fiscal 2003.

      Orders booked in the fourth quarter from continuing operations were
$5,210,000 compared to $3,232,000 last year and for the 2004 fiscal year were
$17,109,000 compared to $16,348,000 a year ago. Backlog at quarter end was $16.4
million (approximately $7.5 million is shippable within one year) as compared to
$16.7 million (approximately $7.7 million shippable within one year) in the
fourth quarter of the prior year.

      Cash and cash equivalents at March 27, 2004 was $2,752,000 compared to
$5,005,000 as of March 29, 2003. Based on current operations, Giga-tronics
believes that it has sufficient cash and cash equivalents to fund its cash needs
for approximately five to eight quarters. To operate beyond that term, the
Company must either earn additional cash from operations, obtain a line of
credit or obtain additional funds from other sources.

      During the fourth quarter of fiscal 2004, Giga-tronics consummated the
sale of Dymatix, which had been discontinued during the first quarter. Under the
terms of the sale, the Company will receive $300,000, of which $50,000 was paid
at closing, $50,000 is to be paid in May 2004 and $200,000 is to be paid in
quarterly installments over two years. The Company may receive additional
earn-out payments based on a percentage of sales on a monthly basis over the
next two years.

      Giga-tronics will host a conference call today at 4:30 PM ET to discuss
the fourth quarter and full fiscal year results. To participate in the call,
dial 612-332-0345. The call will also be broadcast over the internet at

call discussion reflects management's views as of May 12, 2004 only.
