Ironwood Electronics introduces its DG-QFN40C-01 socket that is designed for a 5 mm × 5 mm package size, operating at bandwidths up to 40 GHz with less than 1 dB of insertion loss. The sockets are designed to dissipate up to several Watts without extra heat sinking, and they can handle up to 100W with a custom heat sink. The contact resistance is typically 3 m? per pin. The socket connects all pins and the optional center power pad with 40+ GHz bandwidth on all connections. The socket is made with a high performance and low inductance diamond particle interconnect contactor that is capable of 100,000 insertions. The temperature range is -70°C to +200°C. The pin inductance and capacitance to ground both approach zero.
