RFMW Ltd. announces design and sales support for the PE43705, a 7-bit, 31.75 dB digital step attenuator from Peregrine Semiconductor. The PE43705 offers an extremely wide operational frequency range of 50 MHz to 8 GHz. Internal circuitry manages unequal ON/OFF switch times providing a “glitch safe” design by eliminating the unknown attenuation issue that plagues other DSAs.
The PE43705 maintains excellent monotonicity over the entire frequency range. Peregrine’s PE43705 handles up to 31 dBm of instantaneous power with a CW power rating of 28 dBm.
Extednded temperature range of -40 to +105 deg. C and IIP3 of 65 dBm make this an ideal step attenuator for fine step signal conditioning in high power transmitters, repeaters and remote radio heads.
The PE43705 comes in a 5x5 mm QFN package.
