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.
