RF Micro Devices announces the RF2861 single-band receiver front end with an integrated TX LO buffer amplifier designed for CDMA cellular, JCDMA and CDMA450 applications. The RF2861 features a 3 × 3 mm footprint. The RF2861 allows handset engineers to achieve design goals and accelerate time-to-market. The RF2861 amplifies and downconverts RF signals featuring a three-gain state LNA (17 dB of gain control) with an integrated single gain state high IIP3 mixer (8.5 dBm). The device also includes an optional TX LO buffer amplifier and both LNA gain and power down modes are digitally controlled. An off-chip current setting resistor allows adjustable LNA and mixer IIP3 to minimize current consumption. In high gain mode, using a typical RF SAW filter, 25 dB of cascaded gain can be achieved with 2.1 dB noise figure.
