Product Overview
Qorvo’s TGL2208-SM is a packaged dual stage Limiter
fabricated on Qorvo’s proven GaAs VPIN process.
Operating over 2 to 20 GHz, the TGL2208-SM has
< 1dB of insertion loss under small signal operation and
flat leakage of < 18 dBm under large signal input.
The TGL2208-SM is suitable for a variety of systems that
require input protection for sensitive receive
channel components.
The TGL2208-SM is available in a low-cost, surface
mount 14 lead 3 x 3 AIN QFN package comprised of a
ceramic base with a plastic epoxy-sealed lid. TGL2208-
SM is ideally suited to support both commercial and
defense related applications.
Lead-free and RoHS compliant.

Application Information and Evaluation Board (EVB) Layout
RF layer is 0.010” thick Rogers RO4350. Metal layers are 0.5-oz copper. Microstrip 50 line width is 0.021”. The microstrip
line taper at the connector interface is optimized for the Southwest Microwave end-launch connector 1092-01A-5.
The pad pattern shown has been developed and tested for optimized assembly at Qorvo Semiconductor. The PCB land pattern has
been developed to accommodate lead and package tolerances. Since surface mount processes vary from company to company,
careful process development is recommended.

Evaluation Board PCB Mounting Detail
The pad pattern shown above has been developed and tested for optimized assembly at Qorvo. The PCB land pattern
has been developed to accommodate lead and package tolerances. Since surface mount processes vary from company
to company, careful process development is recommended.
Ground / thermal vias are critical for the proper performance of this device. Vias should use a 0.008 in. diameter drill, and
they are solid filled with non-conductive material and over plated shut.
