Description
I Modulator Input. 250 mV p-p into 50
termination, dc coupled. The level shifting and
phase splitting is done on board by the AD830
amplifiers.
Q Modulator Input. 250 mV p-p into 50
termination, ac coupled. The level shifting and
phase splitting is done on board by the AD830
amplifiers.
I CH
Q CH
MODOP
Modulator Output. The differential-to-single
ended conversion is performed by a balun on
the board. Impedance matched to 50
for
130.38 MHz IF frequency.
IFIP
IF Amplifier Input. Single-ended-to-differential
conversion performed by a balun on board.
Impedance matched to 50
for 130.38 MHz IF
frequency.
TXOP
IF Amplifier Output. Differential-to-single-
ended conversion performed by a balun on
board. Impedance matched to 50
for 130.38
MHz IF frequency.
