1P503

Model 1P503 Rev. B Hybrid Couplers 3 dB, 90° Description The 1P503 Pico Xinger is a low profile, miniature 3dB hybrid coupler in an easy to use surface mount package designed for DCS and PCS applications. The 1P503 is designed for balanced amplifiers, variable phase shifters and attenuators, LNAs, signal distribution and is an ideal solution for the ever-increasing demands of the wireless industry for smaller printed circuit boards and high performance. Parts have been subjected to rigorous qualification testing and units are 100% tested. They are manufactured using materials with x and y thermal expansion coefficients compatible with common substrates. Available in both 5 of 6 tin lead (1P503) and 6 of 6 RoHS compliant tin immersion (1P503S). ELECTRICAL SPECIFICATIONS** Features: • • • • • • • • 1.7 – 2.0 GHz.

In the design of these couplers, the even mode impedance was chosen to ‘critically couple’ or slightly ‘over couple’ at mid band to maximize performance and bandwidth. The amplitude balance specification is defined as the difference (in dB) of the signals at the COUPLED port output and the DC port output, when compared to the average output level. PHASE BALANCE In theory, output ports of a backward wave hybrid coupler remain in perfect phase quadrature independent of frequency. In practice, factors associated with the manufacturing processes slightly degrade performance. The specification is typical two to three degrees maximum although in practice, phase balance is statistically better than specified (
