HF Technical Description
Honeywell’s new 28Vdc HF radio advances the performance and capability of our HF systems to meet the emerging needs of the HF market place, while still providing the best value of performance to cost.
The new Primus HF 1050 System is superior to other HF systems in many ways. Among many other features, it allows for the paration of the Power Amplifier and Antenna Coupler. This feature allows the antenna coupler to be located clor to the antenna, improving the effective radiated power of this 200-watt PEP high frequency system.

y Syllabic squelch High* – ud for high strength signals
y Syllabic squelch Low* – ud for low strength signals
y Signal Strength
y Signal to Noi Ratio
Syllabic squelch helps eliminate background noi, yet lets voice signals through.
y Superior Receiver lectivity through triple conversion intermediate frequency (IF) amplification and into digital signal processing
y Improved “weak signal” reception and less noi through improved Receiver Sensitivity: SSB Operation –123 dBm > 10 dB SINAD (typ) (-113 dBm min).
y Lower “receive audio” distortion (SSB) less than 5%
y Robust performance: Low distortion 200 Watt Peak Envelope Power (PEP) transmitter output.
y Quicker tuning: Coupler will match the antenna impedance with a first acquisition tune time <10 conds (nominal), and return to stored tune condition in less than 20 milliconds. This stored tune is placed in a non-volatile memory so that re-tuning will not be necessary for that channel and frequency in that installation as long as the coupler is not removed and antenna impedance does not change.
y Rapid transition from Receive to Transmit
y Lower Transmit & Receive VSWR increas coupler (antenna) effective radiated power and antenna receive signal: Tune to less than 1.5:1 VSWR Typical
y Built-in-test capability for (BIT) diagnostic testing
y U of Digital Signal Processing (DSP) and state of the art surface mount technology enables better reliability and overall performance.
y Unit operation up to 55,000 feet outside the pressure vesl of the aircraft. Unit Certified to RTCA DO-160D and DO-178B Level C

2.1 KRX 1053 Receiver/Exciter
The KRX 1053 remote unit contains the receiver and the exciter for the HF 1050 system. It can be mounted outside the aircraft pressure vesl for operation at any altitude up to 55,000 feet. The exciter generates a low power transmit signal, which is fed to the power amplifier in the KPA 1052. Superior receive performance is achieved by a triple conversion receiver which employs digital signal processing, providing higher fidelity demodulation and a variety of squelch types.
The KRX 1053 supports external SELCAL (SELective CALling) option. A standard SELCAL decoder (not furnished with the HF 1050 System) is required for operation. In a SELCAL equipped aircraft, the pilot can have the audio volume turned down completely or squelched to relieve background noi during flight. In order to contact the aircraft, a coded audio signal is nt, which is decoded by the SELCAL decoder on board the aircraft, which caus a visual or audio signal to be generated notifying the crew of the call.
2.2 KPA 1052 Power Amplifier
The KPA 1052 Power Amplifier is all solid-state. The PA mounts in a horizontal orientation, and can be mounted up to 50 feet away from the Antenna Coupler. It can be mounted outside the aircraft pressure vesl for operation at any altitude up to 55,000 feet and shock mounts are not required. T
he KPA 1052 amplifies the signal from the KRX 1053 Receiver/Exciter into a 200 watt peak envelope power (PEP) transmitted signal in single sideband operation or 50 watts of carrier power in AM operation. After filtering, the amplified signal is fed to the KAC 1052 antenna coupler. In the receive mode, the signal is pasd through the KPA 1052 to the KRX 1053 receiver.
2.3 KAC 1052 Antenna Coupler
The KAC 1052 Antenna Coupler is mounted near the HF antenna to maximize transmission efficiency. The KAC 1052 can be mounted in either the vertical or horizontal position,
outside the aircraft pressure vesl for operation at any altitude up to 55,000 feet, and shock mounts are not required. The antenna coupler matches the impedance of the antenna to the 50 ohm output of the transmitter. A microprocessor in the KAC 1052 controls the antenna coupling function and exchanges information with the controller via the KRX 1053.
A bridging amplifier is included in the design of the KAC 1052 allowing elimination of external bridging amplifier for dual HF installations. The KAC 1052 also keeps data in on-board non-volatile
memory of all previously successful tuning solutions and us this tuning data on subquent tunes within the same frequency range.
2.4 PS 440 Primus II Select HF Controller
The PS 440 is a new ARINC 429 HF control head. It operates as a stand-alone controller in either single or dual HF installations. Selections of frequency or channel operation, emission modes, squelch and various options (i.e. ITU, Clairifer, HF Data Link, etc) are made by rotating two concentric knobs on the front panel. Two other concentric knobs, with a center push button, are ud to lect the operating frequency or programmed channel, and entering information into memory. Also, three push buttons are ud for lecting emergency frequencies, performing lf-tests, and lecting various ttings. Information is displayed on a ries of LCDs occupying two rows along the top of the controller.
3. Datalink Capability (Future Path Definition)
3.1 Design Objective
新东方英语听力下载
The HF 1050 design provides a clear growth path to support future requirements for HF data link communications. Although there is limited u for HF data link today, operators will need HF to support voice and data in the future to take full advantage of the benefits that will be available when CNS/ATM is fully implemented. The initial HF 1050 will meet the technical specifications to support data, and can be upgraded in the future to full data link capability without the need for an additional LRU. The KRX 1053 external connector pin numbers have already been designated for the HF data link so that harness wiring can proceed to be ready for the KRX 1053 with HF data link capability.
