NEC's SPDT switches hit the mark (New Devices)
Santa Clara, CA. NEC s new UPG137GV and UPG138GV are L-Band single pole double throw (SPDT) GaAs-based MMIC switches developed for digital cellular, PCS and WLAN applications. These devices feature a wide bandwidth, low insertion loss and high P1dB. The UPG137GV operates on a +3 to +5 V control voltage, while the UPG138GV operates from 3 to 5 V. Both devices are housed in an 8 pin SSOP package and are available on tape-and-reel. For the L- and S-band, the company has also introduced a low insertion loss GaAs SPDT switch. Based on a GaAs FET process and designed for PCS, WLAN, WLL and Bluetooth applications, the UPG158TB operates from 300 MHz to 2.5 GHz and is housed in a 6 pin (2.0 1.25 0.9 mm) super mini-mold package. High linearity switching is offered, and a Pin (at 1 dB) of +26.5 dBm and Pin (0.1 dB) of +23.0 dBm, for a control voltage of 3 V. www.cel.com
