Abstract
A low noise block converter feedhorn (LNBF) is disclosed. The LNBF comprises a PCB, a dielectric resonator oscillator (DRO), a chamber, a tuning screw, and a cover. The DRO is placed on the PCB. The chamber has a first partition, and the first partition is used to cover up the DRO. The chamber further comprises a round hole. The tuning screw passes through the round hole and is then used to adjust the oscillating frequency of the DRO. The cover is used to cover up the tuning screw in order to restrain the DRO from power leakage through the gap in between the round hole and the tuning screw.
