Description
The HS8775F-04 is a single-pole four-throw (SP4T) switch designed for antenna/impedance tuning applications which requires very low insertion loss and high voltage handling capability. It can also be used for multi-mode GSM/GPRS/EDGE/WCDMA/LTE transmit/receive applications. The HS8775F-04 is controlled by a standard GPIO interface for easy control. The HS8775F-04 includes an integrated LDO (Low Drop Out) regulator, which enables operation over a very wide supply range. No need for external DC blocking capacitors unless DC is applied externally. The HS8775F-04 is manufactured in a compact, 10- pin 1.1 x 1.5 x 0.58 mm package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.
