... T/R and diversity switches achieve good insertion loss and isolation without degrading the overall linearity. The switches can be controlled with CMOS logic levels. The AM55-0003 is ideally suited for QPSK, BPSK or other linearly modulated systems in the 2.4 GHz ISM frequency band. It can also be used in GFSK systems where levels of +25 dBm are required. Typical applications include WLAN and wireless portable data collection. This power amplifi ...
