Chip protects antenna in mobile handsets

Milpitas, Calif.—California Micro Devices announced the PicoGuard CM1282, a single channel ESD (electrostatic discharge) protection device for the FM radio, GPS, Bluetooth and WLAN antennas used in advanced mobile handsets.

The CM1282 features low capacitance (0.5 pF) antenna port protection and low insertion loss (<-0.25 dB) through 1.8 GHz. It offers what CMD says is dynamic resistance that is more than 30% lower than competing products, and clamping voltages that are 20% lower than competing products. Additional features include 8kV contact discharge protection per IEC 61000-4-2 Level 4 and low leakage current. The CM1282 meets the linearity mask for 802.11 protocols.

The CM1282-01D1 is available in an industry standard, compact SOD-882 lead free, RoHS compliant package.

Pricing: Samples are priced at $0.06 each at 3,000 units.
Availability: Mass production is planned for April 2009.
