Band Select Filter with a notched band in the UWB passband in order to avoid being interfered by the other radio signals. 
Lowpass filter (LPF):
A lowpass ﬁlter is required in wireless communication systems in order to suppress harmonics and spurious of power ampliﬁers and oscillators and to eliminate the outband noise
Transmitter and receiver switch: High isolation, high linearity and power handling capacity
Low Noise Amplifier (LNA) :
The SNR required for a BER of 10−3for AWGN channel is over 10 dB. (Bit error rate (BER) corresponding to the bit error probability )
Variable Gain Amplifier (VGA): offer an adjustable gain and normalize the average amplitude of the signal to a reference value.
Power Amplifier (PA): convert a low-power radio-frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter.
Down/up convert the signal to the basband/passband.
Analog Digital Converter (ADC):
Sampling and Quantization (distortion)
Digital Analog Converter (DAC):
Modulation: (Converts digital data to a continuous waveform suitable for transmission)
Mixer, synthesizer and VGA and ADC and DCA
The most powerful part: all the digital stuff
Source coding, channel coding and detection
As the UWB is proved failure, the Intel proposed the WiGig for next generation and the frequency is over 60 GHz and data rate is 5 Gbps.
