Sirenza Microdevices has expanded its silicon germanium (SiGe) active mixer product family with the addition of three new mixers for use in the transmitter line-up in wireless-infrastructure installations.
The SMDI STM-1116, STM-2116 and SRM-3116 SiGe active transmit mixers, covering frequency bands from 800 MHz to 2.5 GHz, achieve low LO-RF leakage while providing high-linearity IF-to-RF conversion for cellular base station applications. STM mixers include on-chip RF, IF and LO buffers, providing a high-performance, compact implementation of the up-converting function for base-station transceivers. All three ICs are packaged in industry-standard 16-pin, exposed-pad TSSOP plastic packages.
"With the addition of the STM series of mixers, Sirenza Microdevices is continuing to provide its customers with increasing levels of integration and functionality," stated John Pelose, vice president of wireless products. "SMDI's STM products are the first-ever SiGe active mixers designed specifically for the base-station IF-to-RF up-converting function. We believe this family of new products will provide equipment manufacturers a more integrated, high-performance solution than that presently achieved using a traditional passive mixer approach."
Samples and fully assembled evaluation boards are available now from Sirenza Microdevices. Production quantities will be available in September 2002.'"
