Power amps enable high linearity transmitters

San Jose, Calif.—Endwave Corp. released two power amplifiers 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 the transmit power amplifiers measure 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-in. rack-mount configuration for instrumentation applications. In this form-factor, the rack-mount units operate off 120 to 240 VAC and include all the necessary AC-to-DC conversion, power line filtering and conditioning internal to the unit.

Across frequency variants, the power amplifiers employ 85% common parts. Popular add-on options include customizable bias features, linear variable attenuators for power control, on-board output power monitors and built-in temperature compensation.

Call the factory for frequency band coverage, including S, C, and X-bands to cover WiFi, WiMAX, and other communications bands.
