RF Micro Devices Intros RF2861 Front-End Solution
RF Micro Devices Inc. (Greensboro, NC), a provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, announced production availability of 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 small, 3x3mm footprint, which is designed to optimize board space and minimize cost for handset manufacturers.
The RF2861 meets industry demands for reduced package size while adding increased functionality with its integrated TX LO buffer amplifier. The RF2861 amplifies and down-converts RF signals featuring a three-gain state LNA (17dB of gain control) with an integrated single gain state high IIP3 mixer (8.5dBm). 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, 25dB of cascaded gain can be achieved with 2.1dB noise figure.
Manufactured in a silicon germanium process, the RF2861 is offered in a 3mm x 3mm QFN package with full ESD protection on all pins. The RF2861 is priced at $1.88 in quantities of 10,000 units. Samples, fully assembled evaluation boards and production quantities are available now.
