Patent number: 9509419Abstract: A communication circuit includes a receiver path, a frequency translating loop filter and a signal source circuit. The frequency translating loop filter includes an auxiliary mixer, and a frequency translating filter backend circuit such as a filter. The signal source circuit can be shared with a transmitter path. When the receiver path receives an external signal, the auxiliary mixer and the frequency translating filter backend circuit perform high-frequency filtering. When the receiver path need not receive the external signal, the auxiliary mixer up-converts a low-frequency auxiliary signal provided by the signal source circuit to a high-frequency domain, and the up-converted signal is received by the receiver path. Thus, an operation parameter of the receiver path can be adjusted and calibrated according to a response of the receiver path.Type: GrantFiled: June 5, 2014Date of Patent: November 29, 2016Assignee: MStar Semiconductor, Inc.Inventors: Ming-Yu Hsieh, Po-Yang Chang, Tzu-Chin Lin, Yi Lu
