IRONWOOD ELECTRONICS SG-MLF-7103 high performance elastomer socket for 1.27mm pitch QFN package is designed for a 6.15mmx5.15mm package size and operates at bandwidths up to 30GHz with less than 1dB of insertion loss (GSSG configuration). The contact resistance is typically 20 milliohms per pin. Network analyzer reflection measurements for the G-S-S-G case were taken with all except the pins under consideration terminated into 50 Ohms. Device is mounted using supplied hardware on the target pcb with no soldering, and uses tiny footprint. This allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. Product incorporates a simple hardware installation method so that IC’s can be changed out quickly.
