MAST BAND AMPLIFIER SERIE AMB 600-N DESCRIPTION Broad band amplifier, suitable for individual systems or small installations in low signal level areas. Operates with a wide range of input levels. The circuit, which is housed in a metal box, provides a high degree of isolation between inputs and outputs, as well as immunity from radio-electric interference. The set is covered with a plastic housing, which protects it from ultraviolet radiation and bad weather conditions. The housing is designed for easy fixing on the mast. • Direct antenna connection. Very low noise figure. • Independent level regulation for each input. • Notch filters for selective level regulation of two UHF signals. • Protected against atmospheric disturbances and radio-electric interference. • Connection point for output level TEST. • Designed with SMD technology Power supply 24 V ± 5% o Operating temperature range – 20 ÷ 60 C TECHNICAL SPECIFICATIONS MODEL Reference Number of inputs Frequency range Gain Output level DIN 45004B (-60 dB) Input/output impedance Min. input level For S/N = 30 dB Gain regulation Noise figure Attenuation in the TEST output UHF selective Equalization (Notch) FM rejection 27 MHz rejection (CB) Current drawn Packing dimensions Weight (1) (2) AMB 610 N 36810 1 BI/BIII UHF dB 30 40 (1) AMB 631 N 36831 2 BI/BIII 30 UHF 40 BI/BIII 20 UHF 30 BI/BIII 30 UHF 36 UHF 36 AMB 632 N 36832 3 BI/BIII UHF1 UHF2 30 40 40 106 Ω 75 dBµV 37 34,5 37 34,5 37 34,5 dB dB 25 5 19 2,5 25 5 19 2,5 25 5 19 2,5 dB dB dB dB mA mm Kg UHF1: 21-37 UHF2: 38-69 A UHF1: 21-41 UHF2: 43-69 R UHF1: 21-45 UHF2: 49-69 S UHF1: 21-47 UHF2: 48-69 T UHF1: 21-29 UHF2: 30-69 U UHF1: 21-56 UHF2: 57-69 V UHF1: 21-39 UHF2: 41-69 UHF2: 32-49 AMB 620 NF 36821 dBµV N UHF1: 21-31 AMB 620 N 36820 UHF3: 50-69 37 25 5 19 5 37 19 5 25 5 35 19 3 19 3 (2) AMB 632 NF T 36842 BI/BIII 30 UHF1 20 UHF2 40 BI/BIII 30 AMB 640 N 36840 4 UHF1 UHF 36 36 37 47 35 37 35 25 5 19 15 19 5 25 5 19 3 19 3 UHF3 36 19 3 30 0-15 dB (470 MHz) 0-6 dB (830 MHz) 38 — 0-15 dB (470 MHz) 0-6 dB (830 MHz) 35 20 44 155 x 110 x 45 4,5 — 0-15 dB (470 MHz) 0-6 dB (830 MHz) 25 — 50
