RFMD unveils multiple GAN-based amplifiers for cable applications

October 18, 2012 // By Paul Buckley
RF Micro Devices, Inc. has unveiled multiple leading-edge GaN-based CATV amplifiers which include the RFPD2940 – a best-in-class, high-power GaN-based CATV power-doubler amplifier, as well as a new family of GaN-based push-pull CATV amplifiers, led by the RFPP2870 and RFCM3080.

RFMD’s RFPD2940 GaN-based CATV power-doubler amplifier delivers unprecedented output power (+63 dBmV) without compromising the critical linearity performance requirements of CATV applications. The superior output power of the RFPD2940 enables CATV network operators to upgrade existing systems to wider bandwidths, enabling higher data throughput while also reducing operating expenses. The RFPD2940 CATV power-doubler amplifier operates from 45 MHz to 1000 MHz, has 23 dB gain at 1000MHz, features superior input and output return loss of -20 dB, and delivers better than -73 dB CTB and CSO performance. The RFPD2940 is housed in an industry-standard SOT-115J package and is available today for immediate sampling.

RFMD’s RFPP2870 and RFCM3080 GaN-based push-pull amplifiers are ideally suited to drive GaN-based final stage CATV power-doubler amplifiers. The RFPP2870 and RFCM3080 feature 28 dB gain at 1003 MHz, have excellent input and output return loss (-20 dB typical), and deliver low distortion levels of -68 dBc CTB and -75 dBc CSO. The RFPP2870 is housed in an industry-standard SOT-115 package, and the RFCM3080 is housed in a miniature 11 mm x 8.5 mm multi-chip-module (MCM) surface mount package.
