From the project
30 - 6000 MHz 10 dBm Transmitter based on MAX2871 synthesizer. Controlled by Teensy 3.2.
30 - 6000 MHz 10 dBm Transmitter based on MAX2871 synthesizer. Controlled by Teensy 3.2.
Some parts of the circuit design based on H. Forsten's home made VNA. The microwave transmitter consists of following blocks:
Synthesizer is based on MAX2871 chip (PLL with integrated VCO) and its loop filter. This guy is able to synthesize frequencies from 25 MHz to 6 GHz. Filter bank that makes sure no harmonics are generated in GHz range. Amplification block that uses programmable attenuation for the gain control and 12 dB power amplifier TRF37A75. Coupler and RSSI detectors that measure emitted and…

Microwave-Transmitter: common questions
What microcontroller does the Microwave-Transmitter use?
The Microwave-Transmitter is built around the Teensy3.2, from the NXP family.
How big is the Microwave-Transmitter PCB?
The Microwave-Transmitter measures 88.9 × 35.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Microwave-Transmitter?
144 components, from 64 distinct parts. The full bill of materials is listed on this page.
Where can I download the Microwave-Transmitter design files?
From the PeraZver/Microwave-Transmitter repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Microwave-Transmitter design in my own project?
Yes, under the terms of its GPL-3.0 license, which PeraZver chose for the repository.
Can I test firmware for the Microwave-Transmitter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
