5G mmWave Base Station and UE Testing: 5G NR FR2 bands n257 and n258 center around 28 GHz, where device output power is limited and propagation losses are severe. Characterizing UE transmitters, small cell power amplifiers, and beamforming antenna modules requires measuring signals that arrive at the analyzer well below -80 dBm after test fixture losses. The P32 preamplifier ensures the analyzer has sufficient sensitivity headroom for EVM, ACLR, and spurious emission measurements at these frequencies.
Ka-Band Satellite Ground Segment: Ka-band satellite uplinks (27.5–31 GHz) and downlinks (17.7–21.2 GHz) involve testing earth station amplifiers, BUCs (block upconverters), and feed assemblies where test signals can be quite weak after filtering and directional coupling. The P32 preamplifier provides the sensitivity margin needed for noise figure estimation, gain characterization, and spectral purity verification of satellite ground equipment.
mmWave Component Characterization: Evaluating mixer conversion loss, LNA gain/noise figure, and filter insertion loss at 26–32 GHz often produces output signal levels well below -60 dBm. Without a preamplifier, your measurement accuracy degrades as signals approach the analyzer noise floor. The P32 keeps your measurement in the linear, accurate region of the analyzer's dynamic range.
