Peregrine Semiconductor Announces 8 GHz SP4T RF Switch for Test-and-Measurement/ATE Applications

The result is a highly-linear switch that is well suited for applications requiring highly-linear RF performance and fast settling time, such as Test and Measurement, and Automated Test Equipment.

The absorptive PE42540 switch is comprised of four symmetric RF ports, with high isolation RFX to RFX of 45 dB @ 3 GHz, 39 dB @ 6 GHz, and 31 dB @ 8 GHz. On-chip CMOS decode logic facilitates a two-pin low voltage CMOS control interface and an optional external VSS feature. Additionally, the switch features high linearity of 58 dBm IIP3, with high ESD tolerance of 2 kV HBM on RFC, and 1 kV HBM on all other pins. It also has a maximum input-power-handling capability of 30 dBm @ 8 GHz into 50 Ω.

“The PE42540 switch complements our PE42551 and PE42552 switches with extended frequency and low insertion loss,” said Mark Schrepferman, director of marketing for Peregrine’s High-Performance Solutions business unit. “We believe this is the industry’s highest-performance SP4T switch, in terms of bandwidth, insertion loss, and linearity.”

The PE42540 switch is available in a 32-lead, 5 mm x 5 mm QFN package, for $4.87 each, in 10,000-unit quantities. Samples and volume-production quantities can be ordered in late June through Peregrine’s global sales representatives and worldwide distribution partners.
