Digital NetRadios®
Multi-band power amplifier
PA-2504

Product Specifications

• The product is designed for amplifying radio signals in the frequency range of 30 - 520 MHz to a power of up to 20 Watts when connected to the antenna terminals of radio devices (with nominal output power of radio devices ranging from 1 to 4 Watts).

• The product provides amplification (when operating in the transmit mode) and transmission (when operating in the receive mode) of radio signals in the frequency range from 30 to 520 MHz

• The product provides 1W amplification gain of the input signal by 13 ± 2 dB at a nominal signal level at the input of the product.

• The level of attenuation (attenuation coefficient of the received signal) of the radio signal within the operating frequency range of the product when operating in the receive mode does not exceed 2 ± 0.5dB.

• Note: under the influence of destabilizing factors, an increase in the attenuation coefficient of the received signal by 1.4 times is allowed.

• The product ensures operability when the product is powered by a voltage of 12V to 20 V.

• Consumed current of the product at rated power supply voltage 13.8±0.5V:

  • Rx (receive) mode: no more than 0.3 ± 0.15 A;

  • Tx (transmit) mode: no more than 4.5 ± 0.3 A.

• The product ensures operability after a short circuit or break from disconnection of the Antenna-feeding device at the antenna output for at least 1 minute.

• Requirements for weather resistance:

  • The product complies with the requirements of specifications under conditions of exposure to high humidity of 100% at a temperature of +35°C.

  • The product complies with the requirements of technical specifications under conditions of exposure to low ambient temperatures of -30°C.

  • The product is able to withstand extreme cold temperatures of -50°C.

  • The product complies with the requirements of specifications under conditions of exposure to elevated ambient temperatures of +55°C.

  • The product withstands the impact of changes in ambient temperature in the temperature range from the lower limit of -50°C to the limit of increased +55°C.

• The product is supplied as packed in an antistatic bag with metallization, moisture indicator and silica gel desiccant.

• Overall dimensions (HxWxD): 141×102×40.5mm ±0.5 mm.

• The mass weight: 0.7 ± 0.05 kg.
