RF Transceiver Design Mention any four components of a regenerative satellite transponder that you know. As a RF design engineer, consider afull duplex communication link(simultaneous reception andtransmission) through a satellite

withthe following requirements: The uplink signal is 145 MHz while the downlink is at 435 MHz; A 20 W power amplifier is used on the uplink with 25 dB gain;and It is necessary to provide a low pass filter on the uplink to passonly the 145 MHz uplink signal while rejecting any noise powerin the 435 MHz band. Briefly explain the two RF components design techniquesfor anoptimum performance.[6 Marks) The following are the specifications for a 145-MHz low-pass filter designfor this satellite link: Chebyshev response with 0.1 dB passband ripple; a passband cut-off frequency (not the -3 dB frequency) at 160MHz; at least -40 dB rejections at 435 MHz. i) order of the filter; left-half plane poles.
