An RF switch for broadband consumer applications including cable televisions (CATV), digital television (DTV), multi-tuner digital video recorders (DVR), set-top boxes, PCTVs and video game consoles has been released by Peregrine Semiconductor Corporation.
The switch has been manufactured using the company’s UltraCMOS technology. The enhanced single-pole, double-throw (SPDT) device features high linearity and isolation performance in both powered and unpowered states, to address the broadband requirements of the FCC 15.115 specification. The RF switch features isolation of 63dB at 1 GHz (typically). Isolation levels are maintained in the unpowered state in compliance with the FCC 15.115 standard for CATV-to-antenna isolation. During unpowered operation, the ports are terminated to prevent reflected signals between the terrestrial and cable antennas.
