Dual-Band LNA/Mixer Eyes CDMA Handsets

Designed specifically for the North American dual band/tri-mode CDMA handset market, the RF2489 LNA/mixer is a complete dual band, tri-mode receiver front end containing two LNAs, three mixers, local oscillator divider circuitry and LO buffer outputs. The device performs all of the front end receive signal processing required for dual band, tri-mode applications.
The design permits the bias currents to be set using off-chip current reference resistors for both the LNA and mixer blocks. Its flexibility allows the conversion of received CDMA, AMPS or GPS RF signals to intermediate frequency in dual band, tri-mode, dual mode or PCS platforms. Price is $2.31 each/100,000.
