Embodiment Construction
[0028] As mentioned in the background section, the problem faced in the prior art is that the output impedance of the low noise amplifier does not match the input impedance of the test equipment, resulting in inaccurate testing of radio frequency parameters of the low noise amplifier.
[0029] The embodiment of the present invention provides an on-chip testable low noise amplifier with an output impedance adjustment unit to meet the input impedance requirements of the test equipment, so that the test equipment can test the radio frequency parameters of the low noise amplifier more accurately.
[0030] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
