Mitsubishi Offers SAW Filters with Low Insertion Loss for Worldwide Mobile Communication Systems

Business Wire, Dec 15, 1998

SUNNYVALE, Calif.--(BUSINESS WIRE)--Dec. 15, 1998--The Electronic Device Group of Mitsubishi Electronics America Inc., today announced the North American availability of the MF1081V and MF1082V series families of surface acoustic wave (SAW) filters, which offer customers low insertion loss and excellent pass band ripple performance. The MF1081V and MF1082V families are designed for Rx-Band (1930 - 1990 MHz) and Tx-Band (1850 - 1910 MHz) PCS CDMA wireless handset applications, respectively. The new SAW filter families both feature an extremely small 3.0 x 3.0 x 1.2 mm footprint, helping designers to decrease the size and weight of their portable end products.

Both SAW filter families offer devices optimized for either stopband rejection or insertion loss. For example, in the Tx-Band, stopband rejection for the MF1082V family is typically a minimum of 18 dB from 0 to 1500 MHz and a minimum of 23 dB from 3700 to 3820 MHz, with a maximum insertion loss of 4.2 dB and a maximum pass band ripple of 2.5 dB. The MF1081V family has similar performance characteristics in the Rx-Band. Both families offer a broad operating temperature range of -30 to 85 degrees Celsius.

"The ever increasing consumer demand for smaller and lighter personal communications devices continues to push designers and their designs to the limit, searching for the perfect match between size, performance and cost," said Vincent Verret, senior product marketing manager for microwave and RF products at Mitsubishi Electronics America. "Mitsubishi's new MF1081V and MF1082V series SAW filter families provide competitively priced, highly effective surface mount solutions that are capable of satisfying customers' wireless handset system requirements."

Mitsubishi Electronics offers additional SAW filters in frequency bands ranging from 100 - 2000 MHz, with a wide selection of stopband rejection and insertion loss characteristics.

Packaging, Pricing and Availability

Available in tape and reel packaging, Mitsubishi's MF1081V and MF1082V series SAW filter families are completely surface mount compatible. Both families are available in production volumes, priced at $3 each in 1000-unit quantities.
