Microwave Transmitter

30 – 6000 MHz synthesizer with power amplifier

For a long time I wanted to crown my work in RFwith a self made synthesizer. I have picked Henrik Forsten’s home made VNA design with MAX2871 as a reference, modified the schematics and routed to my needs. I use Teensy 3.2 for all digital control.

ATtiny85 breakout with selectable LEDs

ATtiny85 breakout with selectable LEDs

While working on the oven heater control circuit for the Voltage Reference Quad Project V2, I needed a small board for testing the PIDheater control without using a serial port or display. I also wanted to use the same board design for multiple projects where I only needed a few I/O pins.

 

 

The ATtiny85 (PDIP) breakout board includes an array of 5 low current blue LED’s that are solder jumper selectable for each of the ATtiny85’s I/O pins except for the reset pin.

Barbouri has shared the board on OSH Park:

Network Analysers: The Electrical Kind

Instrumentation has progressed by leaps and bounds in the last few years, however, the fundamental analysis techniques that are the foundation of modern-day equipment remain the same. A network analyzer is an instrument that allows us to characterize RF networks such as filters, mixers, antennas and even new materials for microwave electronics such as ceramic…
