Fairview Microwave Inc. has released the new line of bi-phase modulators that cover the broad octave frequency bands from 0.5 to 40GHz. These new devices use TTL logic to phase modulate data onto an RF carrier signal using 2 phase-shift keyings (2PSK).

 

The new series includes nine models of 0° to 180° bi-phase modulators that deliver impressive performance such as low insertion loss of 2.5 dB typical, the fast switching speed of 40 nsec typ, low VSWR of 1.8:1 typ and maximum peak RF input power of 0.5 watts. All designs require dual bias voltages, and input and output RF ports are bi-directional.

 

The new Bi-phase modulators come in compact and rugged packages that utilize solder pins for TTL control, DC bias, ground, and field-replaceable SMA or 2.92 mm female connectors. With high reliability, all the models meet the MIL-STD-202 environmental test conditions for humidity, shock, vibration, altitude, and temperature cycle.

 

The new Bi-phase modulators can be used in a variety of applications like military and commercial communications systems, microwave radio, radar, high-data-rate test and measurement, serial data transmission, and wireless base station infrastructure

 

Features of the Bi-phase Modulators

  • Broadband frequency coverage from 500 MHz to 40 GHz
  • Comprehensive selection of 9 models offered
  • TTL level digital bitstream is encoded onto the RF carrier
  • 2 Phase Shift Keying (2PSK) modulation at 180° and 0°
  • Low insertion loss: 2.5 dB typical
  • Compact packaging with SMA or 2.92 mm RF female connectors
  • High peak input power handling up to 0.5 watts
