Anadigics supplies Samsung with InGaP HBT PAs

Anadigics Inc. is supplying CHP1237 InGaP HBT (indium gallium phosphide heterojunction bipolar transistor) power amplifier (PA) modules (PA) to Samsung Electronics for the SPH-S2300 CDMA phone with embedded 3.2 megapixel digital camera.

The CHP1237 InGaP PA module offers high levels of efficiency and linearity for the 1750- 1780MHz frequency band used for South Korean PCS CDMA applications. This module utilizes proprietary Passive-Free Technology (PFT) to integrate the entire power amplifier function into a small 3mm-by-3mm by 1mm module.

Ali Khatibzadeh, VP of wireless products at Anadigics, said, "Our proprietary Passive-Free Technology has allowed us to design one of the industry's lowest profile 3mm-by-3mm CDMA PA modules without sacrificing functionality."
