The LPA-8220 1-kW Power Amplifier, all mounted on a pre-wired custom cabinet for ease of installation and maintenance.

The Sunair LPA-8220 (1kW) HF Power Amplifier is a component of Sunair’s 8220 series wideband HF transmitter system, primarily used in defense, security, and aviation communications for reliable, high-power long-distance communication. Note that the similar, but more common, model is the Sunair LPA-9600 1kW amplifier.

Key Features
  • Redundant Design: The amplifier utilizes a modular “soft-fail” design with redundant internal AC power supplies and multiple amplifier modules (four in the LPA-9600). This allows the unit to automatically switch to a lower power output (e.g., 500W) in the event of a module failure, ensuring continued operation.
  • Rugged and Reliable: Designed for continuous duty in demanding environments, the amplifier is built to military standards (MIL-STD-810F for shock and vibration) for use in marine and land-based applications, including shipborne, shelterized, and fixed station installations.
  • Comprehensive BITE (Built-In Test Equipment): The unit incorporates microprocessor-controlled BITE capability, with status indicators and an English language readout on the front panel that displays the cause of any malfunction, simplifying maintenance.
  • Wide Frequency Range: The LPA amplifiers operate over the full HF frequency range of 1.5 MHz to 30 MHz.
  • VSWR Protection: The amplifier delivers rated output into a load VSWR of up to 2:1 and is protected from damage at load VSWR above 3:1 (graceful degradation occurs between 2:1 and 3:1).

RCU-8310 RCU
Sunair RCU-8310 Remote Control Unit The Sunair RCU-8310 is a full-function remote control unit, now capable of operating up to eight (8) transceivers, transmitters, or receivers from the 8400 series. The next-generation RCU is equipped with a larger 7-inch TFT display, which is now touchscreen, along with keyboard entry. Its front panel is physically identical to the front panel of the unit it controls. This ensures operational simplicity. The RCU offers a full set of operating modes, including AME, NB-FM, USB, CW, Data, as well as remote control of Automatic Link Establishment (ALE) functions when the RT-8400 is equipped with the internal ALE option. These capabilities match the operating modes available on the radio itself. The RCU-8310 also allows remote operation of Sunair peripheral equipment including the F-9810 PreSelector/Post-Selector, the LPA-8210/8220 Power Amplifiers, and the CU-9125/CU-9150 Antenna Couplers. It is possible to connect the RCU-8310 to the remote radio using RS-232/RS-422 for short distances, Ethernet for longer distances, or leased lines (requires the optional internal FSK modem). Advanced built-in-test (BITE) capability provides feedback to the lowest replaceable unit (LRU) level for both the local RCU as well as the companion 8400 series radio. The remote control’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. ● Remote Control via Serial and Ethernet ● Controls Multiple Radios ● Comprehensive BITE to LRU ● Identical to Radio Front Panel ● Analog or VoIP Audio Interface ● Secure Digital Voice (MELPe S4591)
F-9810B PRE-SELECTOR
Sunair F-9810B Pre/Postselector The Sunair F-9810B Pre/Postselector permits operating collocated (co-site) Sunair radios, whether the RT-8500WB Transceiver or any radio of the 9000E Series, on frequencies with as small as a 10% separation. The Sunair F-9810B is controlled by the Sunair radio it serves. As a pre-selector, the F-9810B provides an additional front-end selectivity stage, thus reducing the receiver desensitization and overload that normally occurs in the presence of strong adjacent RF transmissions. As a post-selector, the F-9810B rejects spurious outputs and broadband noise in the transmit signal before it reaches the Sunair LPA power amplifiers, thereby limiting interference to collocated receivers. In transmit mode, the F-9810B operates as postselector on the radio’s low output power path. Because of this, the F-9810B is fully operational as postselector with an RT- 8500WB regardless of whether the transceiver is driving the LPA-8200 at 100 mW or operating at its full 125-W output. A separate transmit antenna port provides the flexibility of using either a single antenna for transmission and reception or separate transmit and receive antennas. In addition, the keyline over coax feature prevents damage to the unit from high power RF transmission by reducing the control time delay of transmit-to-receive switching. The F-9810B offers a selectivity of 35 dB minimum (±10%), 40 dB typical, from the nominal tune frequency, with an ultimate rejection of 70 dB minimum. The unit tunes in 10 Hz increments, and tuning time is 10 ms maximum, making the F-9810B suitable for ALE applications. Furthermore, the F-9810B offers two levels of gain. The Pre/Postselector’s intuitive modular design allows for ease of maintenance and upgrade throughout the equipment life cycle at minimal expense. F-9810B • Improved co-site performance • 40 dB typical, 70 dB maximum attenuation • Selectable gain • Individual transmit and receive antenna ports • Automatic tracking 10 ms tuning • Automatic RF overload protection • Automatic by-pass
