Sirenza Microdevices Announces Production Release of New CATV Broadband Amplifier IC.

BROOMFIELD, Colo. -- Sirenza Microdevices (NASDAQ: SMDI) today announced the production release of a new CATV amplifier IC. The CGB-1089Z is designed for CATV network applications, including CATV line drivers, drop amplifiers, optical transceivers and FTTH video applications. This single stage amplifier provides excellent gain flatness across the entire 1 GHz frequency range, supporting CATV signal transmission at higher frequencies for increased bandwidth requirements.

"Throughout the world, CATV service providers and Multiple Service Operators (MSO) are upgrading their networks to increase capacity for additional channels, including digital and high definition channels," stated Richard Bay-Ramyon, Sirenza's director, broadband and consumer business unit. "The CGB-1089Z is ideal for network upgrades as it delivers flat gain across the entire 50 to 1000 MHz range in an industry standard package."

Technical details:

Developed with an InGaP HBT process, the CGB-1089Z features typical gain flatness of 16 dB +/- 0.4 dB across the 50 to 1000 MHz frequency range. Signal distortion is a low -77 dBc CTB, -65 dBc CSO. Excellent return loss (21 dB IRL) and a single 5 volt supply make the CGB-1089Z easy to implement. The CGB-1089Z is housed in the low cost, surface-mount SOT-89 package and is RoHS / WEEE compliant. This device has an ESD rating of class 1C (1KV HBM) in accordance with Sirenza's 3R's program for reliable, rugged, and robust performance.

The CGB-1089Z is available for immediate shipment. Pricing is $1.38 each at 10K pieces. Samples and applications support are available by contacting Sirenza at [e-mail].
