GENERAL DESCRIPTION
The ADAR5000 is a 1-to-4 Wilkinson power splitter that is designed
for space-sensitive microwave signal distribution applications. Excess
insertion loss ranges from −1.5 dB to −2.5 dB from 17 GHz
to 32 GHz. The four outputs are matched in both phase and
amplitude, making the ADAR5000 ideal for signal distribution applications
requiring low time skew between channels. The ADAR5000
can also be used as a combiner, combining input signals at the P1,
P2, P3, and P4 ports to an output at the S1 port. The ADAR5000 is
housed in a compact, 2.460 mm x 2.460 mm x 0.500 mm WLCSP,
which makes it ideal for use in planar, phased-array antenna systems
that require a tight pitch between elements.
The ADAR5000 is fabricated on a passive silicon process, and it is
specified to operate from −40°C to +85°C.
