Ironwood's BGA transceiver socket works up to 10 GHz
The socket's small footprint allows inductors, resistors, and decoupling capacitors to be placed very close to the device under test for impedance tuning.

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 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.
The SG-BGA-7154 costs
$294 for a quantity of one. Reduced pricing is available for higher quantities.
