Peregrine revamps SOI mixer range
RF SOI (silicon on insulator) company Peregrine Semiconductor has announced the UltraCMOS PE4152, a high linearity mixer with integrated local oscillator (LO) buffer with bypass mode. The launch of the PE4152 kicks off Peregrine's initiative to revamp its mixer portfolio and is the first of many Peregrine will release this year.
Successor to the PE4150, this quad MOSFET mixer is said to offer RF engineers more design flexibility while delivering exceptional linearity, high isolation and low conversion loss. The PE4152 is suitable for land-mobile-radio (LMR), tactical radio and cellular infrastructure applications.
"The PE4152 mixer gives RF engineers more flexibility in their designs," says Kinana Hussain, director of marketing at Peregrine Semiconductor. "If the customer chooses to bypass the integrated LO buffer, they can tap into the mixer core's raw performance. This design flexibility provides a one-chip solution to customers who previously would have had to use two separate designs to achieve optimum performance."
The PE4152 mixer operates from 100 to 1000 MHz (RF) and 200 to 900 MHz (LO). When using the LO buffer, linearity is 25 dBm IIP3 and isolation is 30/30 dB LO-RF/IF. In LO bypass mode, linearity is 24 dBm IIP3, and isolation is 60/58 dB LO-RF/IF. Conversion loss is less than 6.6 dB in either LO mode.
