Sirenza Microdevices Announces Production Release of New Active Bias SiGe Amplifier Line, the SGC Series.

BROOMFIELD, Colo. -- Sirenza Microdevices (NASDAQ:SMDI) today announced the expansion of its portfolio of silicon germanium (SiGe) products with the introduction of a new low cost, high performance amplifier product family. The SGC product line-up includes ten new SiGe hetero-junction bipolar transistor (HBT) Darlington amplifiers, configured with a patented active-bias network.

"Sirenza's patented active bias design allows performance directly from a 3-volt or 5-volt supply in popular, industry-standard package styles," stated Jeff Gudewicz, Sirenza's director, standard products business unit. "Other active bias solutions typically require a package change and a new printed circuit board layout. The Sirenza solution offers the flexibility to directly implement active bias into existing designs."

The SGC family builds on Sirenza's leadership position in high performance SiGe amplifier ICs. SGC-23, 24, 43, 44, and 63xx product details include:

* SiGe HBT semiconductor process for high performance available at low cost

* Active bias providing:

* Operation directly from a 3-volt or 5-volt supply with no dropping resistor

* Stable performance over temperature

* Consistent product performance

* Operating frequency from 50 to 4000 MHz

* Power levels from +10 to +19 dBm (P1dB)

* High linearity, up to +35 dBm OIP3

* Gains ranging from 16 to 21 dB at 850 MHz

* SOT-363, SOT-86 and SOT-89 package styles

The SGC family provides robust ESD performance, 1000V HBM Class 1C, and features a moisture sensitivity rating of MSL 1. Samples and application design support are available by contacting Sirenza at [e-mail].
