PE4237_15 Datasheet, PDF (1/8 Pages) Lucky Light Electronic – Single 3.0-volt power supply

Product Description
The PE4237 RF Switch is designed to cover a broad range of
applications from near DC to 4000 MHz. This reflective switch
integrates on-board CMOS control logic driven by a single-pin,
low voltage CMOS or TTL control input. Using a nominal +3-
volt power supply, a 1 dB compression point of +32 dBm can
be achieved. The PE4237 also exhibits outstanding isolation
of better than 43 dB at 1000 MHz and is
offered in a small 3x3 mm DFN package.
The PE4237 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.

Notes: 1. Device linearity will begin to degrade below 10 MHz.
2. The DC transient at the output of any port of the switch when the control voltage is switched from Low to
High or High to Low in a 50 Ω test set-up, measured with 1ns risetime pulses and 500 MHz bandwidth.
