Preliminary Data Sheet
Product Description
The SRQ-2116Z is a high-linearity, silicon germanium direct
demodulator designed for direct conversion and low-IF base-
station receivers. This device features high second- and
third-order intermodulation suppression, high LO-RF isolation
and excellent quadrature accuracy.
The SRQ-2116Z outputs are directly coupled and are capable
of driving loads as low as 50 Ohms and can drive reactive
loads without additional components such as damping resis-
tors. This device is packaged in a RoHs compliant and Green
16-pin TSSOP with matte tin finish. The package includes an
exposed paddle for improved thermal and RF ground.
