Fujitsu's new F6CE SAW filters -- now available in production quantities -- are the first designed specifically with the very small footprint and light weight required for product development in the rapidly-emerging PCS market. Packaged in 3mm x 3mm x 1.2mm surface mount housings, the F6CE filters weigh less than 0.1 gram and can handle up to 100mW of input power.
The two new SAW filters are part of the F6Cx family, which covers frequencies of 1.0 to 2.5 GHz. The F6CE-1G8800-L2XA has a center frequency of 1880 MHz and a passband 60 MHz wide, covering the Transmit band of the newly-allocated Licensed PCS spectrum. Typical performance parameters for the L2XA include insertion loss of 3.5 dB, in-band ripple of 1.5 dB, and in-band voltage standing wave ratio (VSWR) of 1.8.
The other new filter, the F6CE-1G9600-L2XB, is designed with a center frequency of 1960 MHz and a passband of 60 MHz to cover the Receive band of the Licensed PCS spectrum. Typical performance parameters include insertion loss of 4.0 dB, in-band ripple of 2.0 dB, and in-band VSWR of 1.8.
"The F6Cx family provides the highest performance in the smallest package available for use in the handsets and base station infrastructure equipment required for the PCS Licensed Bands," said Dennis Burman, telecommunications marketing manager at FMI. "They have already been designed into several advanced PCS products that are being developed by industry leaders in North America."
"Fujitsu has been a technology leader in UHF SAW filters and other communications ICs for many years, and the introduction of these two new very high-performance bandpass SAW filters continues that leadership," he added. "The introduction of the F6Cx series illustrates the aggressive roadmap that Fujitsu has put in place to define telecommunications products to meet the rapid advances in wireless communications."
The new F6Cx filters are being manufactured using Fujitsu's lithium tantalate technology, which provides excellent temperature stability, with integrated 50 Ohm impedance-matching networks. The technology also ensures that the filters will demonstrate excellent "roll-off" characteristics, meaning the signal attenuation increases very quickly as one moves from in-band to out-of-band frequencies.
Pricing for both new SAW filters, which are now available in production quantities, begins at $5.95 in 100,000-piece volumes.
