CEL has announced the availability of the CEL CG2409 family of high power RF switches. These devices route high frequency signals through transmission paths and can be used for diverse range of applications including WLAN, mobile communications, wireless security, wireless home automation, digital TV and many other RF products.

The CG2409 is available in two packages X3 and M2. The CG2409X3 and CG2409M2 are manufactured using state of the art pHEMT technology and are packaged and tested in Japan to guarantee high quality and reliability.

These RF switch components can be used within an application to switch between Transmit/Receive modes, as diversity switches, switching between two different antennas, and also switching between RF frequency bands.

The CG2409X3 is a wideband, high-power single-pole, double-throw (SPDT) GaAs MMIC RF switch, specified for the frequency range of 0.05 to 6 GHz, and can operate at a control voltage from 1.8-V to 5-V. The P0.1dB compression point of the switch is 37.5 dBm at 3-V.  The second and third harmonic specs are -80 dBc and -85 dBc respectively at input power of 26 dBm. The insertion loss ranges from 0.3 dB to 0.6 dB while the isolation ranges from 32 dB to 28 dB over the frequency range. The device is in a compact 6-pin XSON package (1.5- x 1.5- x 0.37-mm).

The CG2409M2 is also a high-power single-pole, double-throw (SPDT) GaAs MMIC RF switch but is specified for the frequency range of 0.05 to 3.8 GHz and operates at a control voltage from 1.8-V to 5-V. The P0.1dB compression point of the switch is 36.5-dBm.  The second and third harmonic specs are -80-dBc and -85-dBc respectively at input power of 26-dBm. The insertion loss ranges from 0.35-dB to 0.6-dB while the isolation ranges from 35-dB to 21-dB over the frequency range. This device is in a small 6-pin surface mount package (2.0- x 1.25- x 0.9-mm).
