This circuit, ideal for those who have signal problems in the UHF band, mainly in the reception of digital TV, has a gain of 15dB. The transistor supports good gain equivalent with ft above 1 GHz and special care must be taken with the layout of the board and shields. The 150nH shocks are formed by a wire loop 26 with a diameter of approximately 0.5 cm. The capacitors must all be ceramic and appropriate connectors must be used. The power is low current, about 20 mA is sufficient, and there is no need for regulation. L1 and L4 are formed by 3 turns of wire 28 in the form of 0.5 cm without core. Small changes in the coils may be necessary to obtain the best performance.
