Front-end Modules

This project is concerned with creating RF front-end modules, such as PAs, LNAs and filters, that can be used together with an SDR platform in order to create a custom wireless solution.

Dual PA and Tuner

Dual-channel PA module based around Sony wideband (UHF-3800MHz) configurable MMIC power amplifier and Sony 2-Bank (5-bit series cap-array and 4-bit shunt cap-array) tuner devices, with USB configuration via Atmel AVR microcontroller, which also provides external GPIO for e.g. antenna switching or filter insertion via coaxial relays.

  • Frequency range: 0.3 – 3.8GHz
  • Gain (W-CDMA): min 9.6dB, max 42.1dB
  • Power Output (W-CDMA): min 11.1dBm, max 19.9dBm
  • Power Supply: 5V from USB3 (optional via external power source)
  • Interfaces: SPI, GPIO
  • Connector: Micro USB2 (on PC plugged into USB3 for max I = 0.9A)
  • Board size: 63 x 40mm (PCB: 40 x 40 mm)
  • Heatsink size: 28 x 29 x 15mm

Dual LNA

A compact dual-LNA board with 2x TriQuint TQP3M9005 devices with the following characteristics:

  • 50 – 4000 MHz
  • 15.3 dB Gain at 1.9 GHz
  • 0.8 dB Noise Figure at 1.9 GHz
  • 14 dB I/O Return Loss)
  • +34 dBm Output IP3
  • +22.3 dBm P1dB
  • 50 Ohm Cascadable Gain Block
  • Unconditionally Stable
  • High Input Power Capability
  • Single Supply, 50 mA Current

SAW Filters

SISO modules with a single SMA socket and plug, with TX and RX SAW filters from SAWNICS for bands: I, II, V, VII.
