Abstract
Systems and methods using the systems of testing radio frequency receivers include a radio frequency receiver testing device that has a PIN switch adapted to receive a radio transmission, a thermal diode coupled to the PIN switch and controlling the amount of noise within the PIN switch, and a noise diode providing a stable noise source to the radio frequency receiver testing device.
Claims20
A radio frequency receiver testing device, comprising:
- a PIN switch adapted to receive a radio transmission;
- a thermal diode coupled to the PIN switch and controlling the amount of noise within the PIN switch;
- and
- a noise diode providing a stable noise source to the radio frequency receiver testing device.
1 more element
A method of testing a radio frequency receiver, comprising the steps of:
- coupling a radio frequency receiver testing device to an input of a radio frequency receiver;
- receiving a known radio frequency signal at the radio frequency receiver testing device;
- tuning the radio frequency receiver testing device to determine at least one of drift in gain of the receiver, noise floor and noise figure of the receiver, bandwidth getting through the receiver, linearity of the receiver, and stability of the receiver.
