← Back to Rack Mount Amplifiers
Rack-mount amplifier subsystem, 20–520 MHz, 120 W Psat, LDMOS design with universal power supply and forced-air cooling. Broadband, high efficiency, low distortion, with built-in control and protection circuits.
| Electrical Specifications (@ 220 VAC, 25°C, 50 Ω) | |
|---|---|
| Operating frequency | 20 – 520 MHz |
| RF output power @ Pin = 0 dBm (Psat) | 120 W typ |
| RF output power @ P1dB | 100 W typ |
| Power gain | 50 dB typ @ Pin = 0 dBm |
| Gain flatness | ±2 dB |
| Input return loss | ≤ -10 dB |
| Harmonics @ 80 W | -10 dBc |
| Spurious signals | -55 dBc |
| Input / output impedance | 50 Ω |
| Operating voltage | 180 / 220 / 230 VAC (min / typ / max) |
| Power consumption | 660 W typ @ 100 W CW |
| Mechanical | |
| Dimensions (W × H × D) | 482.6 × 88.1 × 445 mm (19 × 3.5 × 17.5 in), 2U bench-top / rack mount |
| Weight | 20 kg (44.1 lbs) max |
| RF connectors | Input: SMA female; Output: Type-N female |
| Cooling | Built-in internal forced-air cooling |
| Environmental (design to meet) | |
| Ambient temperature | -20°C to +50°C (operating case temperature up to +85°C) |
| Non-operating (storage) temperature | -45°C to +85°C |
| Relative humidity (non-condensing) | 95% max |
| Absolute Maximum Ratings & Protection | |
| Input RF drive without damage | +5 dBm max |
| Load VSWR protection | @ Pout = 80 W: infinite VSWR (all load phase and amplitude) for 1 minute; 3:1 continuous; > 5:1 – protection shuts the system down |
| Thermal overload | Power degrades gracefully when ambient temperature exceeds 85°C |
| Control & Options | |
| Enable | TTL logic low (< 0.7 V) |
| Monitoring | RS422 serial management: enable, current / temperature / voltage / forward / reverse sense, current / temperature / voltage / VSWR alarms |
| Options (refer to factory) | LCD status monitor (current, temperature, voltage, standby, fault indication); LAN |
| Note | Do not cover the air duct. |
