40 GHz Impedance Matching Circuit Design
Budget: $3,000 – $5,000 USD
I need an L-network impedance matching circuit designed for discrete frequencies: 18 GHz, 22 GHz, 26.5 GHz, 30 GHz, 33.2 GHz, and 40 GHz. The circuit should handle 5 watts and match a source impedance of 50 ohms.
Load impedance will be measure at each frequency and the data will be shared. However, the device is an electric initiated device (EID) with a DC resistance of 1 ohm across the bridgewire. The anticipated inductive impedance is as follows: 18 GHz=1130.97, 22 GHz=1382.97, 26.5 GHz=1665.04, 30 GHz=1884.96, 33.2 GHz=2086.02, and 40 GHz=2513.27.
For convenience, we would like the matching circuit design to allow for series injection across the EID in line with the GCPW trace. Create two pads on either side of the cut for the initiator leads. Keep the gap and pad geometry as small and symmetric as you can to minimize extra inductance.
Microstrip stub line element circuit type is preferred
We would also like a 2.4 mm female connector on the 50 ohm source side to connect to our amplifier.
Perfect match at each frequency is ideal, but our goal is to ensure that at least 5 Watts of power can be delivered through the EID at each frequency, assuming a 20 Watt RF source is used.
Ideal skills and experience:
- RF circuit design expertise
- Experience with L-network configurations
- Knowledge of high-frequency behavior up to 40 GHz
- Proficiency in impedance matching techniques
