PMI's line of Bi-Phase Modulators includes a comprehensive selection of 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.

PMI's 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.
