Preliminary PHEMT GaAs IC Transmit/Dual Receive Switch With Diversity Antennas 0.5–2 GHz AS160-86 Features MSOP-10 ■ Five RF Ports PIN 10 ■ Transmit to Either of Two Antennas ■ Receive From Either of Two Antennas ■ Differential Biasing for High Linearity Description The AS160-86 is a PHEMT GaAs IC transfer and SPDT switch. This switch is ideal for dual band applications where TX/RX diversity is required. The switch has 4 control lines that may be positive, negative or a combination of both (differential biasing). This switch is designed for commercial wireless applications such as GSM, DCS and PCS systems.
