RF Micro Devices today announced the availability of its RF2861 single-band receiver front end with an integrated TX LO buffer amplifier designed for CDMA cellular, JCDMA and CDMA450 applications.
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).
An off-chip current setting resistor allows adjustable LNA and mixer IIP3 to minimise 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.
Manufactured in a silicon germanium (SiGe) process, the RF2861 is offered in a 3x3mm 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.
