BGA transceiver socket operates at up to 10 GHz
-- Test & Measurement World, 2/1/2010 2:00:00 AM
Used for prototyping and testing 0.5-mm pitch, 51-pin wafer-level BGA devices, the SG-BGA-7154 socket from Ironwood Electronics operates at bandwidths of up to 10 GHz with less than 1 dB of insertion loss. It accommodates a package size of 4x4x0.8 mm and supports all currently used UMTS bands, including the different regional frequency requirements of Europe, Asia, North America, and Japan.
You can mount the SG-BGA-7154 on the target PCB (printed-circuit board) with no soldering. The socket connects all pins with 10-GHz bandwidth on all connections. Contact resistance is typically 20 mΩ per I/O. The socket’s small footprint allows inductors, resistors, and decoupling capacitors to be placed very close to the DUT (device under test) for impedance tuning.
This ZIF (zero insertion force) socket is constructed with gold-plated wires embedded within the elastomer, which serves as the interconnect material between the DUT and the PCB. The elastomer is suitable for applications operating at temperatures ranging from –35°C to +100°C. Pin self-inductance is 0.15 nH, and mutual inductance is 0.025 nH. Capacitance to ground is 0.001 pF. Current capacity is 2 A/pin.
