This paper describes the design procedure for quadrature hybrid for UHF band. Circuits are based on distributed parameters with anticipated manufacturing on a PCB. Emphasis is put on a compact size, three methods are used for size reduction of transmission lines. All designs are simulated in electromagnetic simulation software. The best design using meandered lines is verified by measurement with no detectable deviation from target working frequency. Temperature simulation is conducted with the best design.
