    摘要： The present invention relates to a receiver chip used in a Digital Video Broadcasting (DVB) receiver, and more particularly, to a Digital Video Broadcasting-Handheld (DVB-H) receiver chip employing a diversity scheme. In the DVB-H receiver chip according to the present invention, a first receiver block 101 and a second receiver block 102 isolated from the first receiver block are packaged within one receiver chip. An I/O terminal of the first receiver block 101 is connected to an external pin of one side 120 of the receiver chip, and an I/O terminal of the second receiver block 102 is connected to an external pin of a side 130 opposite to the one side 120 of the receiver chip. A source terminal or a control terminal of the first or second receiver block 101 or 102 is connected to the external pin of one or more of the one side 120 or the other sides 110 and 140 of the receiver chip. The first receiver block 101 comprises a first Low-Noise Amplifier (LNA) 311, a first mixer 312, a first filter 313 and a first a Variable Gain Amplifier (VGA) 314. The second receiver block 102 comprises a second LNA 321, a second mixer 322, a second filter 323 and a second VGA 324. A Voltage-Controlled Oscillator (VCO) supplies a frequency to the first and second mixers 312 and 322.
