23 cm SSPA
SSPA 23cm - top side view. Two pairs of PA blocks are mounted symmetrically on two overlapping heat-sinks in the middle (cooling air inlet at the center of bottom plate). There are two combiners (3dB hybrids) sitting on the top of each pair of PA bloks on the left and right side. N connectors provide PA outputs from combiners while SMA connectors are used on inputs.
