The CG25-QFN-2003 high-performance elastomer socket for 0.4-mm pitch QFN packages is designed for a 5×5-mm package and operates at bandwidths up to 40 GHz with less than 1 dB of insertion loss (GSSG configuration). The contact resistance is typically 20 mΩ per pin. Network analyzer reflection measurements for the GSSG case were taken with all except the pins under consideration terminated into 50 Ω. The socket is mounted using supplied hardware on the target PCB with no soldering and uses the smallest footprint in the industry. The footprint allows inductors, resistors and decoupling capacitors to sit close to the device for impedance tuning. The socket also incorporates an integrated compression plate inside the clamshell socket lid so ICs can be changed out quickly.
The CG25-QFN-2003 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is -35C to +100°C. The pin self-inductance is 0.06 nH and mutual inductance of 0.019 nH. Capacitance to ground is 0.129 pF and mutual capacitance is 0.017 pF. Current capacity is 2 A/pin.
Pricing for the CG25-QFN-2003 from Ironwood Electronics is $382 at qty 1; with reduced pricing available depending on quantity required.
