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

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.  Quantic PMI Model PEC-35-614R5-VGC-SSPA provides 30 to 37 dB of gain from 5.85 to 14.5 GHz.  The power output at 1dB compression is greater than 22 dBm and 2nd harmonics are internally filtered to provide more than -30 dBc rejection.  An integrated linearized analog attenuator provides up to 35 dB 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: (500 MHz to 18.0 GHz)

This amplifier operates over the 500 MHz to 18.0 GHz 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.

Broadband Positive Gain Slope Amplifier for Gain Correction within SIGINT and DF Systems: (20 MHz to 1.0 GHz)

This amplifier operates over the 20 MHz to 1.0 GHz 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.  This model offers 6.9 dB of gain at 20 MHz and then slopes up to 19 dB of gain at 1.0 GHz.  This model offers a remarkably high OIP2 of greater than 50 dBm while maintaining a low noise figure of 8.0 dB typical.  These are currently being used in airborne applications.  Please contact us with your specific requirement.  We can design the amplifier so that the gain curve matches your exact cable loss profile.

High-Isolation - Fast Switching - Limiting Amplifier - TTL Controlled

This amplifier operates over the 14.0 to 16.0 frequency band.  It provides a limited RF output and has an ON / OFF blanking feature.  A TTL signal can select isolation (blanking) mode which provides greater than 60 dB of attenuation.  The attenuation switching speed is less than 10 ns.

Limiting Amplifier with Excellent Harmonic Rejection and Output Power "BIT" Circuit

This amplifier was designed to provide ultra-flat gain response from 5.6 to 8.4 GHz.  This amplifier provides 25 dB of gain and a limited output power of 19 ±2 dBm.  This amplifier contains integrated low-pass filters to suppress 2nd harmonics while in a limiting condition.  A BIT "TTL" circuit is incorporated on the output of the amplifier to monitor the amplifier's output power level.

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

This amplifier has a single input and two outputs that operate over the 6.0 to 18.0 GHz frequency range.  Features include Single RF Input - Dual Multiple Gain Outputs; AC Coupled RF Input and Output; and Internally Regulated / Reverse Voltage Protected.  Output #1 provides 23 to 27 dB of gain, while Output #2 provides 13 to 17 dB 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.

OC-192 10 GBit/s and 12.7 GBit/s LN/MZ Modulator Driver

This amplifier was designed for the commercial fiber optic market.  This fiber optic driver is priced extremely low when compared with other suppliers.
