DATA SHEET AS172-73, AS172-73LF: PHEMT GaAs IC Transfer Switch 300 kHz–2 GHz Features Pin Out High linearity (50 dBm IP3 @ 0.9 GHz) @ 3 V ● Low insertion loss (0.4 dB @ 0.9 GHz) ● Isolation (20 dB @ 0.9 GHz) ● Simultaneous T/R switching ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 Positive Operation ● External Antenna J2 CBL CBL 5 V1 CBL 4 3 J1 Internal Antenna CBL Description 10 kΩ The AS172-73 is a PHEMT GaAs IC 4 port switch designed to combine T/R and antenna changeover switching capability within one device. This switch has two controls and is ideal for applications requiring low power consumption. The AS172-73 has excellent performance to 2 GHz, making it suitable for dual-band handset designs. NEW 2 Tx 6 1 V2 Rx VS DC blocking capacitors (CBL) and biasing resistor must be supplied externally for positive voltage operation. CBL = 100 pF for operation >500 MHz. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
