News Release: RF Monolithics Selected to Provide IF Filters for XM Satellite Radio Receivers

RF Monolithics, Inc. (Nasdaq:RFMI) (RFM) announced today that it has been selected by a leading manufacturer of XM Satellite Radio (Nasdaq:XMSR) (XM) receivers to provide intermediate frequency (IF) surface acoustic wave (SAW) filters for integration with a new generation chipset. This premier supplier of satellite digital receivers (SDAR) provides radio units to the world's leading automotive manufacturers and retail units for electronics retailers nationwide. RFM expects to begin production shipments in its third quarter and to ramp up production in its fourth quarter of fiscal year 2004. No other terms or conditions were disclosed. RFM's filters represent state-of-the-art SAW design and provide the desired intermediate frequency filtering solution for satellite radio receivers. RFM has developed multiple filter products for the satellite digital radio receiver market and has supplied over one million IF SAW filters for SIRIUS (Nasdaq:SIRI) satellite digital radio receivers. Additionally, RFM continues to work with both service providers (SIRIUS and XM), chipset suppliers, and radio manufacturers on next generation products.

'We are extremely pleased to be one of the providers of IF filters for XM's receivers. RFM filters contribute significantly to two of the major technical improvements that make the new-generation XM radio happen. The superior electrical characteristics of our filters contribute to the performance of the radios and the small size of our filters is a key factor that makes the new-generation radios much smaller than the older products,'stated Dr. Jidong Dai, Executive Director of RFM's Communications Product Group. 'Being selected for inclusion in receivers for XM, in addition to SIRIUS, and having our filters in both receivers for automotive OEM and retail satellite radios, underscores our broad penetration of the digital satellite radio entertainment market with leading edge technology.'

Satellite radio has revolutionized traditional car radio by offering consumers added options for music and programming. Satellite radio currently features more than one hundred commercial free stations that offer digital quality music, news, comedy, sports and entertainment. Subscribers to either of the services can enjoy the same station without interruptions from coast-to-coast. Additionally, portable satellite receivers, boom boxes and home entertainment systems are revolutionizing the home audio market. SkyWaves Research Report, a research publication covering the satellite radio industry from SkyWaves Research Associates LLC, Ann Arbor, Michigan, projects that the two satellite radio broadcasters will share between 30 and 48 million subscribers by 2012.
