Bi-Phase Modulator

The FM86GM2000 is a 0° to 180° Bi-Phase Modulator that operates across a frequency range from 500 MHz to 1000 MHz. This modulator takes a TTL level digital bit stream and encodes it onto the RF carrier using 2 Phase Shift Keying (2PSK). 2 Phase Shift Keying utilizes 2 phases which ...The FM86GM2000 is a 0° to 180° Bi-Phase Modulator that operates across a frequency range from 500 MHz to 1000 MHz.

This modulator takes a TTL level digital bit stream and encodes it onto the RF carrier using 2 Phase Shift Keying (2PSK). 2 Phase Shift Keying utilizes 2 phases which are separated by 180°. Impressive typical performance includes low insertion loss of 2.5 dB, 10 nsec speed (10-90% RF), 15 dB carrier suppression, and 0.5W CW maximum RF input power.

The design is bidirectional with input and output RF ports, and employs dual bias voltages (+5/-5 Vdc) and integrated TTL processing to phase modulate the control data onto the RF, and operates across a wide temperature range of -40°C to +85°C. The rugged and compact package uses TTL, Bias, Ground pins, and field replaceable SMA Female connectors. The high reliability design meets MIL-STD-202 environmental test conditions for Humidity, Shock, Vibration, Altitude, and Temperature Cycle.
