Product Description

The OM8775C-25 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 HS8775C-15 is controlled by a standard  GPIO interface for easy control. No need for external DC  blocking capacitors unless DC is applied externally. The  OM8775C-25 is manufactured in a compact, 10- pin 1.1 x 1.5  x 0.40 mm package. A functional block diagram is shown in  Figure 1.
