Description

This is PCB for RX Preamplifier module BOX with 2N5109 transistor, based on W7IUV design. You can use it as high IP preamplifier for RX antennas (beverage, DHDL, flag etc.). Gain is up to 18 dB and there is also build in variable ATT. You can easy set the gain as high as you need! As well you can set right transistor bias with multi turn potentiometer. Two relays offer bypass switching if there is no power supply voltage. You can use external power supply connected to the box or the bias tee box for power over the coax.


Using

  • High IP RX preamplifier - RX antennas
  • Remote RX preamplifier with power over coax
  • Buffer amplifier
  • Driver amplifier

Main functions

  • Broadband: 0.1 MHz to 30 MHz
  • Very high IP3
  • Gain up to 18 dB
  • High output power up to 26 dBm
  • Variable ATT for gain 0 to 18 dB
  • Bypass relays
  • Front-end diode protection - ON/OFF by jumpers
  • Power over coax with the Bias Tee BOX
  • You can set transistor bias as you need by trimmer
  • ONLY PCB

Parameters

  • Supply voltage 12 - 15 V
  • Power directly or over the coax - bias tee - voltage 12 - 15 V
  • Supply current up to 180 mA include relays!
  • Gain up to 18 dB
  • REAL IP3 37 dBm for 18 V / 90 mA (need cooling) - more info on my BLOG
  • PCB size 95x95 mm
  • Designed for PL SO-239 / F connectors

Available as

KIT: all parts + PCB and IP56 box - KIT VERSION
ASSEMBLED: ready to use - ASSEMBLED VERSION
ASSEMBLED SMD version: ready to use - ASSEMBLED VERSION (only PL connector)
