Miniature GaAs MMIC switch targets digital cellular and cordless phones

Dec 11, 2003 12:00 PM

Santa Clara, Calif. -- California Eastern Laboratories has added a new SP3T (single pole triple throw) switch to its offering of gallium arsenide (GaAs) MMIC switches. Developed to serve as a high-power band selection device in CDMA dual band and GPS cellular phones, the new UPG2031TQ operates at frequencies of 500 MHz to 2.5 GHz, so it's also a suitable choice for 2.4 GHz ISM band applications.

At just 2.55 x 2.30 x 0.6 mm, its 10-pin TSON-style "TQ" package has a smaller footprint and lower profile than other SP3T packages. The UPG2031TQ delivers low insertion loss, high isolation, and low harmonic distortion. While typical insertion loss is 0.45 dB at 1.0 GHz and 0.55 dB at 2.0 GHz, the typical isolation is 26 dB at 1.0 GHz and 21 dB at 2.0 GHz. The SP3T's typical PIN (0.1 dB)is +33.0 dBm at 1.0 GHz. And second and third harmonics are 75 dBc (typ) at Pin = +27 dBm. Available now, the UPG2031TQ is priced at $0.79 in 100K quantities.
