Rugged socket handles 40 GHz from −55 to 150ºC

For high-frequency, wide-temperature applications, the SMP-QFN-8008 socket uses a high-performance, low-inductance elastomer allowing 40-GHz operation on all pins.  The socket accepts 10×10-mm packages and operates with less than 1dB of insertion loss to 40 GHz over a temperature range of −55ºC to 150ºC. Further, it is designed with an aluminum compression screw on its double-latch lid that can be customized for up to 100 W with a modified fin design atop the screw and adding an axial flow fan.

On a per-bin basis, the socket’s self-inductance is 0.10 nH, mutual inductance 0.007 nH, capacitance to ground  0.069 pF, and contact resistance typically 15 mΩ. Current capacity is 4 A per pin. Priced at $2,018 ea / 5, the socket uses mechanical hardware for mounting on a pc board (no soldering is needed), and employs a quick insertion method that lets ICs be changed out quickly. The socket’s device-contact mechanism is rated for >500K cycles and its device contact matrix is quickly replaceable.
