MPCM45

Descriptions

The 

Pico Macom MPCM45 is a professional grade high-performance CATV mini-modu-

lator. This modulator accepts any audio-video baseband television signal and provides a 
45dBmV minimum output on CATV channels 2 to 125 (54-806 MHz) while accommodat-
ing HRC and IRC offset frequencies. The unit can be reconfigured to any output channel 
within band by qualified service centers. Up to 12 or 16 units can be installed “mix-and-
match” in 

Pico Macom’s MPC12, MPS12, MPC12R or MPC16 chassis with MPCMA 

agile mini-modulators or 

MPCD mini-demodulators. Its universal design enables it to be 

installed in other manufacturers’ mini-mod chassis. The unit’s phase-locked loop (PLL) 
circuitry and unique multi-stage output bandpass filtering ensure accurate and spurious-
free output. In addition, the 

MPCM45 uses SAW filtering with FCC group delay correc-

tion circuitry to provide superior adjacent channel selectivity. The 

MPCM45 modulator is 

shipped with all internal adjustments preset. 

Pico Macom backs up this product with its 

industry leading 5-year limited warranty.
