Preamplifier for Microwave Testing
PAM-840A — 18–40 GHz, ~40 dB average gain (applications)
-
mmWave radiated emissions and RF testing across 18–40 GHz for chambers and compact antenna ranges.
-
Mount at the horn (e.g., AH-840) to offset mmWave coax/waveguide loss and surface-finish losses at the feed.
-
Characterize 5G FR2 spurious/harmonics and leakage in 24–40 GHz devices, modules, and small cells.
-
Expose weak high-order content from oscillators, mixers, and frequency multipliers that sit near the analyzer floor.
-
Maintain SNR over longer, higher-loss runs, enabling practical cable routing inside large mmWave chambers.
-
Speed mmWave pre-scans by allowing wider RBW while preserving visibility of narrow, low-level lines.
-
Support antenna pattern checks and quiet-zone verification by lifting low sidelobes and backlobes above noise.
-
Battery operation near the horn avoids supply noise coupling and simplifies placement on booms or masts.
-
Use on receive paths only; not intended for transmit/immunity injection at mmWave bands.
