← Back to Rack Mount Amplifiers
Rack-mount amplifier subsystem, 0.5–3 GHz, 280 W Psat, universal power supply with forced-air cooling. Instantaneous ultra-broadband, 50 Ω matched input and output, unconditionally stable and rugged.
| Electrical Specifications (@ 220 VAC, 25°C, 50 Ω) | |
|---|---|
| Operating frequency | 0.5 – 3 GHz |
| RF output power @ Pin = 0 dBm (Psat) | 280 W typ |
| RF output power @ P1dB | 100 W typ |
| Power gain | 54.5 dB typ @ Psat |
| Gain flatness | ±3 dB |
| Input return loss | ≤ -10 dB |
| Harmonics @ 60 W | -10 dBc |
| Spurious signals | -60 dBc |
| Input / output impedance | 50 Ω |
| Operating voltage | 180 / 220 / 230 VAC (min / typ / max) |
| Power consumption | 1500 W typ |
| 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 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 | @ 60 W: 3:1 – output power degrades to a safe level and the system keeps working; > 5:1 – protection shuts the system down |
| Thermal overload | Power degrades gracefully when ambient temperature exceeds 85°C |
| Control & Options | |
| Enable | TTL logic high (3.3–5 V), internally pulled low; temperature sense 0.5 V + 10 mV/°C; alarm output normally TTL low |
| 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 |
