Biphase Modulators from Fairview Microwave

Fairview Microwave has a new line of bi-phase modulators that includes a comprehensive selection of nine different models which cover broad octave frequency bands ranging from 0.5 to 40 GHz. 

Bi-phase modulators take a TTL level digital bits stream that’s encoded onto the RF carrier using 2 Phase Shift Keying (2PSK) modulation, where the 2 phases are separated by 180º.  This performance is desirable in communications systems, microwave radio, radar, high data rate test & measurement, serial data transmission, base station infrastructure, and other industrial and military applications. 

Fairview Microwave's new line of 0° to 180° bi-phase modulators offer impressive features that include TTL command control, low insertion loss of 2.5 dB typ, 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 the input and output RF ports are bi-directional. These bi-phase modulators operate across a wide temperature range from -40°C to +85°C. 

The compact and rugged packages use solder pins for TTL, DC bias and ground, and field replaceable SMA or 2.92mm female connectors. All designs are highly reliable and meet MIL-STD-202 environmental test conditions for humidity, shock, vibration, altitude and temperature cycle.

Fairview Microwave's bi-phase modulators are in-stock and available for same-day shipping.
