High-Gain, Low-Noise Amplifier Seeks GPS Receivers

Designed for use as an input LNA for GPS receivers, the UPC8233TK boasts a 0.9-dB noise figure that helps improve system sensitivity, while its 20-dB gain helps overcome losses associated with external SAW filters. The amplifier operates at 1.7V to 3.3V, so it is well-suited for applications using the new-generation GPS engines. Typical current consumption is 3.5 mA. It also features a Power Save function that can be controlled directly by the GPS engine’s output logic. The Power Save enable voltage is 1.0V. The UPC8322TK comes in NEC’s miniature 1.5 mm x 1.1 mm x 0.55 mm, 6-pin TK package. For pricing, contact CALIFORNIA EASTERN LABS, Santa Clara, CA. (408) 919-2500.
