Long Wavelength Array Antenna Power Coupler ~ LWAPC
The LWA Power Coupler (LWAPC) provides power to the active balun assembly in the Long Wavelength Array crossed-dipole antenna through the coaxial transmission lines. The LWAPC has two identical RF circuits and is inserted between the antenna assembly and the receivers. It optionally includes a quadrature coupler for discrimination of circular polarizations received by the linearly polarized crossed-dipoles. The LWAPC uses high-quality commercial RF modules and has the same form factor as the Callisto instrument.
