RF switches are an essential component in all modern wireless devices, allowing designers to switch between different antennas and different signal chains. The CG2185X2-C2 is a high dynamic range, low insertion loss, low power consumption, wide range of frequency coverage RF switch. This switch offers unparalleled performance in terms of isolation, linearity, and switching speed. The CG2185X2-C2 is suitable for use in WiFi, cellular, and 4G/LTE applications.

The CG2185X2-C2 is a two-pole, two-throw (2P2T) switch in a miniature lead-frame package. It has one input port and two output ports, with an insertion loss of 0.8 dB typ., and a maximum isolation of 35 dB. The CG2185X2-C2 switch operates from 0.8–3.8 GHz and consumes only 650 mW, allowing it to be used in battery-powered applications.

The CG2185X2-C2 switch supports 1.2:1 maximum VSWR at 3.8 GHz, with a linearity of +38 dBm OIP3 and +18 dBm IIP3. The switch features low-loss HBT technology, wide bandwidth, high isolation and low temperature coefficient.

The CG2185X2-C2 works on the principle of switched-transmission-line technology, using RF lines in non-reflective mode to impedance-match the RF signals at the input and output ports. It operates on the principle of positive RF voltage-controlled switches which use a self-biased diode and a specially designed transmission line to achieve low-loss switching. This type of RF switch offers low insertion loss and high linearity which can help minimize intermodulation distortion and reduce LTE/4G data throughput losses.

The CG2185X2-C2 is a highly recommended RF switch for modern wireless applications, including WiFi access points, cellular networks, LTE base stations, GPS systems, RF instrumentation, CATV, and radio-frequency (RF) test and measurement applications.
