QFN Socket Handles Bandwidths Up To 10 GHz

Operating at frequencies up to 10 GHz with less than 1 dB of insertion loss, the CG-QFN-7003 QFN socket for 0.4-mm pitch, 84-pin QFN devices can dissipate up to several Watts worth of heat without extra heat sinking and can handle up to 100W using a custom heatsink. The socket connects all pins with 10 GHz bandwidth on all connections and mounts via hardware on the target PCB with no soldering. Featuring a high performance, low-inductance elastomer contactor, operating temperature range is -35°C to +100°C. Other features include a pin self inductance of 0.11 nH, mutual inductance of 0.028 nH, capacitance to ground of 0.028 pF, and a current capacity of 2A per pin. Single-unit price for the CG-QFN-7003 is $647. IRONWOOD ELECTRONICS, Burnsville, MN. (800) 404-0204.
