RF Micro Devices Introduces Highly Integrated CDMA Front End Receiver in Reduced Size 3 mm x 3 mm Package

8/13/2002 - RF Micro Devices, a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, announced the production availability of the RF2870 front end receiver.

The RF2870 is a low-cost, highly integrated single-band front end solution that features an integrated transmit (TX) local oscillator (LO) buffer amplifier. The device is assembled in a reduced size 3 mm x 3 mm footprint package and is designed to optimize board space in applications using code division multiple access (CDMA), CDMA IS-95, JCDMA, cdma2000 1x and cdma2000 1x-EVDO standards.

Michael Coady, marketing manager for CDMA products at RF Micro Devices, said, "Board space is extremely valuable in current- and next-generation handsets, especially in 1x-EVDO solutions where system engineers often use two receivers. The RF2870 features an extremely small 3 mm x 3 mm footprint package, reducing the required board space and associated cost, as compared to leading competitive solutions. This solution meets industry demands for reduced package size while adding the increased functionality of its integrated TX LO buffer amplifier and lower noise figure in both the LNA and mixer. In addition to reducing board space, the highly integrated solution helps engineers efficiently achieve design goals and accelerate time-to-market."

Alastair Upton, director of digital cellular products at RF Micro Devices, said, "We continue to see strength in our CDMA receiver business especially at our key customers in Korea and Japan. Over the last 24 months we have delivered over 65 million CDMA small signal products, with a majority of those being silicon germanium-based receivers. The RF2870 fulfills the need for small size and high performance, both of which are required for new cdma2000 1x and 1x-EVDO handsets."

The RF2870 is designed to exceed the IS-98B/D interim standard for CDMA cellular communications. The design offers a three-state gain control to meet IS-98 IMD tests. The device also includes an integrated TX LO buffer amplifier and digital control of LNA gain, mixer gain and power down mode. The RF2870 amplifies and downconverts RF signals with stepped gain control and adjustable IIP3 of the mixer using an off-chip current setting resistor to allow for minimum DC current consumption. The IC features 1.9 dB cascaded noise figure and 25 dB cascaded gain.

Manufactured in silicon germanium, the RF2870 is offered in a 3 mm x 3 mm leadless plastic package. Samples, fully assembled evaluation boards and production quantities are available now from RFMD.
