Small Signal Power Amplifier (SSPA) for TWT Driver Applications: (5.85 to 14.5GHz)       

This amplifier was designed to support TWT manufactures and their need for custom SSPA's.  One standard model is listed below, but we can build these to meet your custom requirement.  PET Model No. PEC-35-614R5-VGC-SSPA provides 30 to 37dB of gain from 5.85 to 14.5GHz.  The power output at 1dB compression is greater than 22dBm and 2nd harmonics are internally filtered to provide more than -30dBc rejection.  An integrated linearized analog attenuator provides up to 35dB of gain control.  Additional RF input and output ports are provided such that an external power linearizer can be installed in the system.

Broadband Positive Gain Slope Amplifier for Gain Correction Applications: (500MHz to 18.0GHz)    

This amplifier operates over the 500MHz to 18.0GHz frequency band and offers a positive gain slope.  This amplifier is useful when trying to correct for a gain loss due to long cable runs.  Many options are available such as frequency range, gain levels and output power levels.  Please contact us with your specific requirement.  We can design the amplifier so that the gain curve matches your exact cable loss profile.

Dual Output - Multiple Gain Amplifier (6.0 to 18.0GHz)     

This amplifier has a single input and two outputs that operate over the 6.0 to 18.0GHz frequency range.  Output #1 provides 23 to 27dB of gain, while Output #2 provides 13 to 17dB of gain.  The unit provides excellent gain flatness over the full bandwidth.  No switching between outputs is required and both output ports are on simultaneously due to the integrated Wilkinson power divider.
