RF Micro Intros RF2890 Front-End Receiver Solution
RF Micro Devices Inc. (RFMD, Greensboro, NC), a provider of proprietary radio frequency integrated circuits for wireless communications applications, announced the production availability of the RF2890 high-performance, dual-band, cellular/GPS LNA/mixer for CDMA and JCDMA applications. The RF2890 meets industry demands for small package size and increased functionality, allowing handset engineers to efficiently achieve design goals and accelerate time-to-market.
The RF2890 includes a three-gain state LNA gain (17.5dB gain control) with an integrated single gain state high IIP3 mixer (8.5dBm). An integrated, optional, LO pre-scaler allows flexible VCO selection. The device also includes a TX LO buffer amplifier. The RF2890 is designed to exceed all TIA/EIA 98D sensitivity, inter-modulation and single-tone requirements, and offers a dedicated, low-current (15.5mA) GPS LNA/mixer with 32.5dB gain. The RF2890 performance can be tailored according to application needs through off-chip bias current reference resistors for both LNA and mixer functions.
Manufactured in an advanced silicon-germanium process, the RF2890 is offered in a 4mm x 4mm, QFN package with full ESD protection on all pins. The RF2890 is priced at $2.45 in quantities of 10,000 units. Samples, fully assembled evaluation boards and production quantities are available now.
