RF2489 Dual-Band/Tri-Mode CDMA Low Noise Amplifier/Mixer
The RF2489 is a high performance CDMA dual-band/tri-mode integrated LNA/mixer. The device is designed to meet all IS-98 sensitivity, intermodulation and single-tone requirements. The operating voltage is 2.7 V and is compatible with 1.8 V logic for control lines. The RF2489 integrates the dual-band LNA/downconverters with 30 dB of gain control and TX LO buffers. Additionally, a divide-by-2 prescaler to allow the use of a single-band VCO is integrated. The design is flexible, in that the bias currents may be set using off-chip current reference resistors for both the LNA and mixer blocks. The device is packaged in a 5 mm x 5 mm leadless plastic package.
