The Pico Macom CA-30RK550 and CA-45RK550 are professional re-broadcast 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 associated 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.
