Description

The АН220-01 (designation РЛТУ.468733.010) is a solid-state HF power amplifier module designed and manufactured by Uranis-Radiosystems JSC, a Russian developer of professional shortwave communication equipment. Covering the complete 1.5–30 MHz HF band, it delivers 150 W (±1 dB) of continuous output power in CW, AM, and SSB PEP modes, with selectable reduced steps of 75 W, 37 W, and 19 W.

Powered from a 27 VDC ±2 V supply drawing no more than 19 A in CW mode, the unit suits vehicle, shipboard, and fixed-base radio installations alike.

A built-in 7-band switchable harmonic filter keeps harmonic content below –50 dB and non-harmonic spurious below –70 dB across seven sub-bands spanning 1.5 to 30 MHz. Dual-channel architecture provides RF-path redundancy: if one channel fails, the amplifier continues operating at 25% reduced power.

An integrated monitoring system tracks output and reflected power, VSWR, operating frequency, input drive, thermal state, and the health of both the harmonic filter and output stages — all accessible via RS232/RS485 interfaces.

The amplifier operates reliably with antenna VSWR up to 5:1, with graceful power reduction rather than shutdown, and includes autonomous protection against short-circuit and open-load conditions. Two-stage overheat protection with automatic fan management ensures reliable continuous-duty operation.

Compact dimensions of 159×164×381.5 mm and an 18 kg weight simplify rack mounting. The operating temperature range of –40 to +55 °C ensures dependable performance across demanding field environments.

Features

📡

Full HF Band Coverage

Operates across the complete 1.5–30 MHz shortwave spectrum via a 7-band switchable harmonic filter with seven sub-bands from 1.5–2.3 MHz up to 20–30 MHz.

⚡

150 W Selectable Output

Delivers 150 W ±1 dB in CW, AM, and SSB PEP modes with switchable reduced power levels of 75 W, 37 W, and 19 W for flexible link budgeting.

🔁

Dual-Channel Redundancy

Two independent amplification channels ensure continued operation at 25% reduced power if one channel fails, eliminating single-point HF path outages.

🔇

High Signal Purity

Harmonics are suppressed to ≤ –50 dB and non-harmonic spurious emissions to ≤ –70 dB, with IMD held to –36 dB (PEP) at 50 Ω and –34 dB under VSWR ≥ 2:1.

🖥️

Integrated Control & Telemetry

RS232/RS485 interfaces provide full remote monitoring — output and reflected power, VSWR, operating frequency, input level, thermal conditions, and module health.

🌡️

Wide Environmental Range

Rated –40 to +55 °C with forced-air cooling and two-stage automatic overheat protection; autonomous protection against short-circuit and open-load antenna conditions.

Buyer Benefits

Continuous-duty capable with automatic thermal management and forced-air cooling, requiring no operator intervention during extended transmissions
Built-in dual-channel redundancy keeps communications on-air at reduced power even after a hardware module failure
Tolerates severe antenna mismatch with VSWR up to 5:1, providing graceful power reduction (97 W at VSWR 2:1 down to 50 W at 4:1) rather than tripping off-line
Complete RS232/RS485 remote control interface simplifies integration into automated communications systems and remote monitoring centres
7-band harmonic filter (≤ –50 dB harmonics) ensures compliance with radio-frequency spectrum regulations in all operating sub-bands
Compact 159×164×381.5 mm form factor and standard 27 VDC powering suits vehicle, naval, and rack-mounted fixed installations without special infrastructure
Gain of 36 dB on a nominal 16±3 dBm drive allows use with a wide range of exciter outputs without additional buffer stages

Applications

Vehicle-mounted and mobile command-post HF communication systems Naval and shipboard shortwave radio installations Fixed-base HF communication and broadcasting stations Military manpack and tactical radio systems requiring compact 27 V amplification Emergency and civil-defence communication networks dependent on reliable shortwave coverage HF data-link and SCADA systems for remote industrial and utility infrastructure Radio relay and repeater stations extending HF network reach Remote telemetry and control systems operating in the 1.5–30 MHz band
