Alpha Industries introduces the AV141-321 Gallium Arsenide (GaAs) IC PHMET voltage variable attenuator that combines price and performance over a high frequency range. Providing high-end performance from 2.7 GHz ( 4 GHz, the attenuator is designed for use in power control applications for 3.5 GHz fixed wireless LAN applications. The AV141-321 has a minimum attenuation of 25 dB, as well as typical insertion loss of 0.7 dB. It also features positive 0.2V to 1.2V control voltage and low cost. Featuring a surface-mount QFN-12 3 × 3 package, the AV141-321 is well suited for high volume applications requiring low cost and high frequency performance.
