Peregrine adds SPDT PE42422 RF switch to its high-linearity, low insertion loss RF switch family

Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency (RF) integrated circuits (ICs) based on silicon-on-sapphire (SOS), has added a HaRP technology-enhanced SPDT PE42422 RF switch to its high-linearity, low insertion loss RF switch family.

Peregrine says that the switch provides linearity of 115dBm IIP2, and 70dBm IIP3; low insertion loss of 0.4dB @ 3GHz, and high isolation of 28dB @ 3GHz. It covers a wide frequency range of 100MHz–6GHz and, using a nominal +3V power-supply voltage, a typical input 0.1 dB compression point of +36 dBm can be achieved. The PE42422 is available in a 2mm x 2mm QFN package, making it suited for general-purpose RF switching applications, such as filter-bank switching in test equipment and base stations, adds the firm.

The 50 Ohm, reflective PE42422 features on-chip, low-voltage CMOS control logic and a wide operating voltage range of 2.3–5.5V, enabling it to be used it in a variety of ways. ESD performance of 4kV HBM for RF pin to ground simplifies manufacturing and improves product reliability. Additionally, with low power consumption of 120 microamperes (typical), the PE42422 switch helps to extend battery life in portable devices.

“As data rates continue to increase, RF designs are becoming more complex, and RF designers require high-linearity, low-loss switches in small packages,” said Mark Schrepferman, director of marketing for Peregrine Semiconductor’s High-Performance Solutions business unit. “By supporting frequencies up to 6GHz, with high linearity, low insertion loss, and availability in the small, 2mm x 2mm QFN package, the PE42422 switch meets these requirements.”

For engineers wanting to evaluate the PE42422 switch, Peregrine has introduced the PE42422 Evaluation Kit (part # EK42422-01, $95.00).

The PE42422 is available in a 12-lead, 2mm x 2mm QFN package for $0.83 each, in 10,000-unit quantities. Samples and volume-production quantities are available now.
