Technical brief
Single-cavity VHF bandpass
Tunable insertion-loss / power trade: 0.5 dB IL at 350 W power-handling, or 2.0 dB IL at 125 W with tighter bandwidth. 6-inch cavity diameter — the workhorse Q for VHF service.
Frequency stability
0.8 ppm/°C — across the operating temperature range, frequency drift stays well below typical channel spacing.
