Detailed Description
20W HF SSB radio can be used to carry the road between the communication or fixed station, with confidentiality machine can perform speech secure communication; with 125W power amplifier, can be used for vehicular mobile communication, a data transmission interface. The station is successfully applied the advanced automatic selection of optimal channel and automatic link establishment ( ALE ) communication technology, using computer control, digital signal processing, has extremely excellent electronic counter countermeasures ( ECCM ) performance, to ensure that in a variety of harsh electronic environment to achieve reliable communication. A: the main technical indicators: 1: frequency range: 2 ~ 29.9999MHz ( channel 100Hz interval ) 2: Job Description: the upper sideband words, words, reported lower sideband 3: frequency stability: ± 1 x 10-6 4: storage channel: 100 5: Power: DC 12V, negative ground. 6:. Power consumption: the state is less than 500mA, sending status less than 5A 7: size: 350 ( mm ) x 260 ( mm ) x 82 ( mm ) B: transmitter performance 1: power output: high-power 20W, small power 5W 2: intermodulation distortion: ≤ - 25dB 3: the unwanted sideband suppression: ≤ - 40dB 4: carrier suppression: ≤ - 40dB C: receiver performance 1: sensitivity: SSB ≤ 1 / /μ V ( S+N / N = 12dB ) CW ≤ 0.5 /μ V ( S+N / N = 12dB ) 2: intermediate frequency, image suppression :≥80dB 3: AGC: from the antenna input terminal 12 u V signal increases 80dB, output variation is less than 6dB 4: audio response : 350 ~ 2800Hz is not inferior to 6dB. 5: power output: output rated 10mV D: automatic link establishment ALE performance 1: adaptive call types: single calling, calling, call 2: channel scan rate: 5 channel / sec 3: in line with the MIL-STD-188-141A standard E: automatic antenna tuning properties 1: automatic antenna tuning time: < 5S 2: precision tuning: In 2 Bobbi superior
