i don't mean ic i mean circuit
:D

If you are testing a transmitter, you can use a diode detector crystal set. Put your receiver antenna next to the transmitter antenna. Then use an oscilloscope to look at the diode output.

To build this you go from left to right: antenna wire, inductor to ground, diode to the output node, shunt capacitor and resistor to ground on the output node.

The inductor has high Z at RF and low at data rate. The capacitor has a low Z at RF and high Z at data rate. The resistor discharges the capacitor following an "ON" and should have a time constant of under 1/5 of a bit duration.

Here is a simple receiver using LM358,you can change it with LP358 to save power.
