Alpha Industries AS202-321
The AS202-321 is a PHEMT GaAs IC SP3T antenna switch operating in the 900 MHz and 1800 MHz frequency bands. When the control inputs are driven with the appropriate voltages, a low insertion loss path is provided from an antenna port to an RX or TX port, while the other ports have high attenuation.| Part No. | AS202-321 |
