Peregrine 8 GHz SP4T switch targets test-and-measurement/ATE applications

Peregrine Semiconductor Corporation (Peregrine) has released the SP4T PE42540 RF switch.  Designed on the latest UltraCMOS® process technology version, STeP5, the HaRP™ technology-enhanced PE42540 switch has a frequency range of 10 Hz to 8 GHz, with insertion loss of 0.8 dB @ 3 GHz, 1.0 dB @ 6 GHz, and 1.2 dB @ 8 GHz.  The result is a switch that is well suited for applications requiring highly-linear RF performance and fast settling time, such as test and measurement (T&M), and automated test equipment (ATE).

The absorptive PE42540 switch is comprised of four symmetric RF ports, with 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 linearity of 58 dBm IIP3, with 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.

Packaging, Pricing & Availability
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.  For more information, visit www.psemi.com.
