Hello im building a remote control and I need a rf mixer for that. Where can I find some cheap ICs.At first I wanted to buy the NE602 chip but it isnt available anymore unless you pay big cash from ebay and my country is very far away from the US so I pay a lot of extra cash for international couriers.

Well i am situated in Europe if you can provide me with a alternative I will be most grateful.

Why do you need a mixer ?
What frequency, bandwidth and RF power remote control are you looking for ?
Most if not all domestic applications have single chip solutions. .

im building a AM transmitter/receiver.I also need 2 antennas and the rest I already have them.

 

Hello,

At wich frequency should the transmitter and receiver work?
What kind of signal should be transfered?
There are ready made modules available.

In the United States there is a 10 milliwatt limit for RF transmissions unless you have a license. Legally it's usually not an issue.

Let's hope the user is sticking to the limits ...

 

As a kid when I started experimenting with electronics, my dad was fond of saying turn it off when his TV reception was screwed up. Sure enough, his TV reception cleared after he said it.

Well i think it would be useful practice for me and would be good to learn practical skills to not buy a packaged transmitter/receiver.
