M/A-COM Introduces New ROHS Compliant 400 - 2500 MHZ, 5-BIT, 15.5 DB Digital Attenuator

LOWELL, Mass, October 6, 2005 - M/A-COM, a business unit of Tyco Electronics and a leading provider of wireless radio frequency (RF), microwave and millimeter wave components, today announced a new RoHS Compliant 5-Bit Serial Controlled Attenuator for applications that require high accuracy and monotonic performance at a low cost.

M/A-COM's MAATSS0022 is a 0.5 dB step GaAs MMIC digital attenuator with 15.5 dB attenuation range in a lead-free MSOP-10 package. The digital attenuator requires external DC blocking capacitors on the RF ports, single positive supply voltage and five individual bit control voltages. The MAATSS0022 is particularly suited for products that require high attenuation accuracy, low insertion loss and low inter-modulation. Typical applications include base stations, wireless data, and wireless local loop gain level control circuits. The MAATSS0022 is fabricated using M/A-COM's GaAs 1.0 micron process. The process features full chip passivation for increased performance and reliability.

Price and Availability
The MAATSS0022 is available from stock and is priced at $1.90 in quantities of 10,000. Contact M/A-COM's domestic and international sales channels for price and delivery quotes. Datasheets and supporting technical documents are available online at
