Giga-tronics and CAP Wireless Collaborate on PA Solution

June 17, 2008

Giga-tronics Inc. and CAP Wireless Inc. announced a joint technology, marketing and support agreement in which Giga-tronics will incorporate CAP’s unique Spatium™ spatial combining technology into its GT-1000A Microwave Power Amplifier. The GT-1000A rack-mount broadband power amplifier, combined with the Spatium engine, delivers outstanding performance and exceptional value for electromagnetic interference/compatibility (EMI/EMC) test, semiconductor evaluation, load pull, antenna range and microwave laboratory applications. Excellent pulse performance and modulated signal fidelity make these amplifiers ideal for defense electronic warfare (EW) and radar testing.


The GT-1000A provides 2 to 20 GHz, 10 W, instrumentation-grade microwave amplification and replaces traveling wave tube amplifiers (TWTA) with rugged solid-state reliability, safe low-voltage operation, no aging characteristics and fault tolerance. The unit saves cost and time and increases reliability by offering 2 to 20 GHz in one instrument and eliminating band switching with multiple amplifiers required with older technology. The solid-state Spatium technology delivers exceptionally broad bandwidth, high power, linearity, low noise (noise figure < 8 dB) and superior harmonics (< -30 dBc, spurious < -60 dBc).

“The integration of CAP’s innovative spatial combining technology within Giga-tronics’ high performance test equipment capability adds a new dimension to the microwave test universe,” said Scott Behan, vice president of marketing at CAP. “The unprecedented combination of broadband solid-state power amplification with broadband signal synthesis provides an extremely broad range in testing from less equipment, saving time, space and money for our customers.”

Rodrick Cross, vice president of sales and marketing at Giga-tronics, added, “We regularly receive requests for one watt and higher output power from our microwave signal generator customers. The GT-1000A has significant benefit as a stand-alone broadband microwave power amplifier, but the combination with a Giga-tronics’ synthesizer offers the remarkable capability of delivering up to 10 watts of leveled output power along with all the other outstanding features of the microwave signal generator.”

Giga-tronics and CAP Wireless will be demonstrating the GT-1000A Microwave Power Amplifier with Spatium technology at the IEEE International Microwave Symposium 2008, June 17-19, in Atlanta, GA, at Giga-tronics’ Booth 1115 and CAP’s Booth 742.
