Ku- and Ka-band Power Amplifiers

January 17, 2011
San Jose, Ca—January 21, 2008—Endwave Corporation, a provider of high-frequency RF modules for telecommunications networks, defense electronics and homeland security systems, has announced the release of two new power amplifiers which deliver excellent power and linearity performance for Ku-Band VSAT networks and emerging broadband satellite communications at Ka-Band. The Ku-band module features 40 dB (min) gain, 0.5 dB (max) gain flatness, typical output power at P1dB of +37 dBm, output 3rd order intercept of +47 dBm (typ), and DC current of 2.6 A @ +15 VDC. The Ka-band module features 27 dB (min) gain, 1.0 dB (max) gain flatness, typical output power at P1dB of +36 dBm, output 3rd order intercept of +43 dBm (typ), and DC current @ +15 VDC of 5.6 A. The noise figures of these transmit power amplifiers are equally impressive, measuring 4.5 dB (max) at Ku-band and 6.0 dB (max) at Ka-band. All units have a maximum VSWR of 2.0:1, without the use of RF input or RF output isolators. These parts are also available in a bench-top 19” rack-mount configuration for instrumentation applications. In this form-factor, the rack-mount units operate off 120-240 VAC and include all the necessary AC-to-DC conversion, power line filtering and conditioning internal to the unit. Across frequency variants, these power amplifiers employ 85% common parts to ensure fast delivery and a robust, repeatable design approach. Other popular add-on options include customizable bias features, optional linear variable attenuators for power control, on-board output power monitors and built-in temperature compensation. Call the factory for frequency band coverage, including popular S, C, and X-bands to cover WiFi, WiMAX, and other communications bands. These products are made possible through Endwave’s acquisition of ALC Microwave. In addition to a world-class line of log amplifiers that ALC has become famous for, ALC has also significantly strengthened Endwave’s overall amplifier product line with impressive additions to Endwave’s power, limiting, low-noise, and general purpose amplifier offering.
