RFMD® Releases High-Performance GaAs pHEMT LNA for Cable Set-Top Box and Digital TV Tuner Applications
Design Win Secured at Leading Set-Top Box and Tuner Module OEM
GREENSBORO, N.C., June 27, 2008 /-- RF Micro Devices, Inc. (Nasdaq: RFMD), a global leader in the design and manufacture of high-performance semiconductor components, today announced the release of the CXE-1089Z GaAs pHEMT LNA for use in cable set-top box and digital television (DTV) applications. The CXE-1089Z is optimized for both low noise figure and low current consumption in order to best satisfy the increasing performance requirements of next-generation, higher-bandwidth devices.
The CXE-1089Z features RFMD's patented active bias circuitry, which stabilizes bias current across changes in threshold voltage related to temperature and process variation, thereby reducing current consumption. The GaAs pHEMT LNA also utilizes a Darlington configuration with an optional external bias control, which further reduces current consumption -- and lowers the thermal profile of the end product -- while maintaining linear RF performance optimized for each application.
Unlike competing devices focused on a single performance parameter, the CXE-1089Z delivers a optimized blend of low noise figure, low multi-carrier distortion and low current consumption, said Alastair Upton, general manager of RFMD's Broadband and Consumer Business Unit. This unique blend of performance combined with our ability to deliver a broad portfolio of CATV products were key elements to RFMD's recent design win at a leading set-top box and tuner module OEM with the CXE-1089Z.
Features of the CXE-1089Z include:
-- Single 5 V supply operation
-- Noise Figure of 2.8 dB typical
-- CTB of -79 dBc and CSO of -66 dBc at 110 channels, +15 dBmV/channel at the input
-- Gain response of 13dB +/- 0.4dB over 50 to 1000 MHz
-- Input return loss of greater than 18 dB
The CXE-1089Z is housed in a compact SOT-89 package, and samples are available immediately. Based on design win activity RFMD(R) anticipates volume shipments of the CXE-1089Z will commence in the current calendar year. For more information about the CXE-1089Z please see rfmd.com/broadbandcatv.
