DESCRIPTION
The RTC56151 is a symmetric, single-pole four-throw (SP4T) antenna switch module (ASM). All inputs and outputs are internally matched to 50 and the DC block capacitors at antenna and each RF ports are not necessary. This feature reduces the parts count, shrinks the circuit size, widens the operating bandwidth, and cuts down the manufacturing costs. Low-loss, high power and high linearity make the SP4T ASM suitable for multimode and multiband applications such as GSM/WCDMA/EDGE. A decoder with low current consumption is included in the device, which uses only two DC voltages to control switch operations. At each RF port to the antenna path, the typical insertion loss is 0.7 dB from 0.5 to 2.5 GHz. The isolation between each RF port is higher th
