Adding a Power Amplifier to an RF IC Circuit

AI Thread Summary
When designing a circuit with the ADF7020 RF IC, ensuring proper impedance matching is crucial, as the power amplifier (PA) requires a 50-ohm input. The addition of the PA alters the combined impedance at the Tx/Rx node, potentially affecting both transmission and reception performance. Utilizing effective simulation tools and test equipment is essential for RF IC and PCBA design. It's important to inquire about available SPICE packages, libraries, and electromagnetic simulation software to aid in the design process. Proper preparation and tools will significantly enhance the chances of successful integration.

Hello all,

I'm trying to design a circuit that utilizes the http://www.analog.com/en/rfif-components/short-range-transceivers/adf7020/products/product.html" . What I'm worried about is getting everything to match properly; the PA requires a 50 ohm input, and after dropping it into the circuit, the combined impedance seen at the Tx/Rx node will change, throwing off both Tx and Rx.

Any suggestions as to where I might begin?

Thanks,
Richard D. Reavis

You really need to have good simulation tools and test equipment to work with RF IC/PCBA design. What tools do you have available? What SPICE package and libraries do you have at your disposal? Do you have any PCBA EM simulation software?
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
