EDS102185 Rev B

STM-1116 SiGe Active Transmit Mixer

800-1000MHz Typical Device Performance (continued)

Note 1: The return losses shown were measured with the STM-1116 mounted on our FR4 evaluation boards . The RF port

was matched for the GSM band, and the IF port matched for 200 MHz. Similar return losses are achievable at other fre-

quencies using standard matching practices.

Note 2: LO-IF leakage measurement has not been adjusted for the loss through the IF (TC1-1) balun.
