GENERAL DESCRIPTION

The ADAR5000 is a 1-to-4 Wilkinson power splitter that is designed

for space-sensitive microwave signal distribution applications. Ex-

cess 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 appli-

cations 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 sys-

tems 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.
