High Performance
Receive Only
800 & 900 MHz Preamplifiers

Features:

• Low noise figure
• High immunity to overload
• Completely shielded
• Suitable for mast/tower mounting
• Small size
• Rugged low profile custom enclosure

Series PXXXVD, PXXXVDA and PXXXVDG preamplifiers have been designed for the most demanding commercial and military applications. Each model has been optimized for the lowest noise figure consistent with excellent strong signal handling capability. These preamplifiers are suitable for use in any receiver or converter/receiver system. Each preamplifier is housed in a rugged low profile custom aluminum enclosure finished with military grade black urethane enamel. Female BNC coaxial fittings are provided for the input and output connections. Other connectors or connector combinations are available. Complete rf shielding is maintained with a feedthrough capacitor for the dc power connection. Mounting holes, suitable for #4 hardware, are located at each corner of the bottom plate.

Gallium Arsenide (GaAsFET) preamplifiers are the only type available in these frequency ranges. Bipolar preamplifier characteristics do not favorably compare with that of the GaAsFET. GaAsFET type preamplifiers offer the lowest noise figure, highest gain and highest immunity to overload of any type device currently available. Each preamplifier model is suitable for fixed location and mobile applications. These preamplifiers are particularly well suited for use in land mobile, cellular, trunking and broadcast STL applications or wherever a low-noise, high-gain preamplifier is required. The wide-band performance of the preamplifiers make them ideal for use in multicoupler installations where low-noise amplification is required over large portions of the band.

Extensive testing of these preamplifiers on existing communications systems indicate that a signal-to-noise improvement of 6-14 dB can be expected. For example, a 10 dB improvement in receiver signal-to-noise performance would give a users 5-watt handheld the same range as a 50 watt unit! Each and every preamplifier is precision aligned on our noise figure measuring equipment and should provide long trouble free operation.

All preamplifiers are designed to be powered by a 10-16 volt dc source with a current consumption of 25 mA. Low power consumption along with the small size make these preamplifiers ideal for installation within existing equipment or systems, or for remote mounting at the antenna. Mounting the preamplifier at the antenna will provide the best system noise figure.
