Peregrine Semiconductor 8GHz Digital Attenuator handles >1W Glitch Free (PE43705)RFMW , Ltd. announces design and sales support for the PE43705, a 7-bit, 31.75dB digital step attenuator from Peregrine Semiconductor. The PE43705 offers an extremely wide operational frequency range of 50MHz to 8GHz. 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 31dBm of instantaneous power with a CW power rating of 28 dBm. Extednded temperature range of -40 to +105 deg. C and IIP3 of 65dBm 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 5x5mm QFN package.
