NEC’s California Eastern Laboratories (CEL) has introduced three new single-pole double-throw (SPDT) gallium arsenide (GaAs) IC switches in a 6-pin TQFN package that’s just 1.0 mm square and 0.37 mm high. Compared to the industry-standard SOT-363 package, these TQFN switches offer a 76% reduction in footprint and a 61% reduction in height. This ultra-low profile gives module designers an alternative to using die in their modules or other height-constrained designs. These new SPDTs operate from UHF to 3 GHz with low insertion loss and high isolation.

Key specifications include control, insertion loss at 2 GHz and isolation at 2 GHz. Insertion loss at 2 GHz is rated at 0.45 dB for UPG2158T5K, 0.35 db for UPG2159T5K, and 0.35 dB for UPG2160T5K. Likewise, isolation at 2 GHz is 19 dB for UPG2158T5K, 25 dB for UPG2159T5K and 18 dB for UG2160T5K. For power handling capability, P1dB is rated at +30.5 dBm, 2.7 V for UPG2158T5K, + 26 dBm, 2.7 V for UPG2159T5K, and +24 dBm, 2.6 V for UPG2160T5K, respectively.

Mass production is slated for August 2005. Pricing at 100K quantities is $0.28 for the UPG2158T5K, $0.28 for the UPG2159T5K and $0.30 for the UPG2160T5K. To help speed circuit design, evaluation boards are available through CEL’s network of sales offices or from Mouser Electronics.
