WIDEBAND RF FRONT-END
One embodiment of the present invention includes a transceiver for wireless communication. The transceiver includes an antenna, a transmitter, which comprises a tunable matching network and a modulator, and a receiver, which comprises a programmable band-pass filter (BPF) and a demodulator.
1 . A receiver for wireless communication, comprising:
an antenna;
a tunable demodulator; and
a programmable band-pass filter (BPF) situated between the antenna and the tunable demodulator.
2 . The receiver of claim 1 , wherein a central frequency of the programmable BPF can be tuned in a range from 300 MHz to 3.6 GHz.
3 . The receiver of claim 2 , wherein the central frequency of the programmable BPF can be tuned dynamically.
4 . The receiver of claim 1 , wherein the programmable BPF includes a tunable low-pass filter (LPF) and a tunable high-pass filter (HPF).
5 . The receiver of claim 1 , wherein the tunable demodulator is a quadrature demodulator.
6 . The receiver of claim 1 , wherein the tunable demodulator has a tuning range between 300 MHz and 3.6 GHz.
7 . The receiver of claim 6 , wherein the tunable demodulator includes a fraction-N synthesizer.
8 . The receiver of claim 1 , further comprising a wideband amplifier situated between the programmable BPF and the tunable demodulator.
9 . A transmitter for wireless communication, comprising:
an antenna;
a tunable modulator; and
a tunable matching network situated between the antenna and the tunable modulator.
10 . The transmitter of claim 9 , wherein the tunable matching network is configured to match an impedance of the antenna over a frequency range from 300 MHz to 3.6 GHz.
11 . The transmitter of claim 9 , wherein the tunable modulator is a quadrature modulator.
12 . The transmitter of claim 9 , wherein the tunable modulator has a tuning range between 300 MHz and 3.6 GHz.
13 . The transmitter of claim 9 , further comprising a wideband amplifier situated between the tunable modulator and the tunable matching network.
14 . A transceiver for wireless communication, comprising:
an antenna;
a transmitter, which comprises a tunable matching network and a modulator; and
a receiver, which comprises a programmable band-pass filter (BPF) and a demodulator.
15 . The transceiver of claim 14 , wherein a central frequency of the programmable BPF can be tuned in a range from 300 MHz to 3.6 GHz.
16 . The transceiver of claim 14 , wherein the programmable BPF includes a tunable low-pass filter (LPF) and a tunable high-pass filter (HPF).
17 . The transceiver of claim 14 , wherein the tunable matching network is configured to match an impedance of the antenna over a frequency range from 300 MHz to 3.6 GHz.
