The Pico Macom CA-30RK550 and CA-45RK550 are professional re-broad-

cast grade push-pull amplifiers producing signals with extremely low noise and

harmonic distortion. In the CA-45RK550, the state-of-the-art hybrid amplifier

module is preceded by a single transistor stage preamplifier to achieve the

total gain of 45dB.The amplifiers are capable of 82 channel operation over the

54-550MHz range.These rack-mounted amplifiers make excellent headend

launch amplifiers and are frequently used in conjunction with Pico Macom’s

passive headend combiners (PHC12G or PHC24G) to overcome losses asso-

ciated with signal combining in CATV and SMATV systems. Also, the

CA30RK550 and CA45RK550 are ideally suited for amplifying the cable input

prior to Pico Macom’s CEF channel elimination filter in applications requiring

“mix-and-match” channel applications or those requiring local insertion. Pico

Macom backs up this product with its industry leading 5-year limited warranty.
