This chapter introduces the system-level design tradeoffs of the RF conversion segment. Software radios require wideband RF/IF conversion, large dynamic range, and programmable analog signal processing parameters. In addition, a high-quality SDR architecture includes specific measures to mitigate the ...
Qorvo’s newest addition to the Active Antenna IC family is the Dual Channel IF Transceiver family. The half-duplex ICs integrate dual Tx single-sideband upconversion, dual Rx image-reject down-conversion functionality, high power PA drivers, and an on-chip synthesizer that enables 2T2R ...
Prior to RF-to-IF down-conversion, a band-select filter (duplexer) and/or image reject filter selects the entire RF band within which the target signal operates. The low-noise amplifier (LNA), which provides amplification of the intended RF band prior to down-conversion, is critical in...
Conversion Loss: 7 dB LO to RF and IF Isolation: >36 dB Input IP3: +18 dBm No DC Bias Required Die Size: 1.45 x 1.45 x 0.1 mm Typical Applications The HMC128 is ideal for: • Microwave & VSAT Radios • Test Equipment • Military EW, ECM, C3I ...
In this brief, the self-reconfigurable gm stage is designed to provide open-loop V-I conversion for the input RF signal and acts as a negative-feedback voltage amplifier for the downconverted IF signal. The RF and IF signal paths are also split by the filtering networks and the feedback ...
