High-linearity switch for CATV CPE / set-top box
Richardson RFPD Inc. announced the availability and full design support capabilities for a UltraCMOS® SPDT RF switch from Peregrine Semiconductor Corporation.
The PE42723 is a HaRP™ technology-enhanced reflective SPDT RF switch designed for use in cable applications, including DOCSIS 3.0/1 cable modem, set-top box and residential gateway. It delivers high linearity and excellent harmonics performance in the 5 to 1794 MHz band, as well as low insertion loss and high isolation performance.
The SPDT switch is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
According to Peregrine, additional key features of the PE42723 include:
• Harmonic performance: o 2fo of -121 dBc @ 17 MHz
o 3fo of -140 dBc @ 17 MHz
• Insertion loss and isolation performance: o Insertion loss of 0.3 dB @ 1218 MHz
o Isolation of 54 dB @ 204 MHz
• ESD performance: 3 kV HBM
• Packaging: 12-lead, 3 mm x 3 mm x 0.75 mm QFN
