PE4150
Product Specification
Evaluation Kit
The Mixer Evaluation Kit board was designed to
ease customer evaluation of the PE4150 Quad
MOSFET Mixer with integrated LO amplifier.

Peregrine Specification 101-0201-00A
The RF and IF ports are connected through
50ohm transmission lines and 1:4 transmission
line transformers to J5 and J7, respectively. The
LO ports are connected through 50 Ω
transmission lines to J4 and J6, respectively, and
can support either a single-ended or differential
signal drive. With a single-ended input, no
termination is needed on the un-used port.
The board is constructed of a two metal layer FR4
with a total thickness of 0.062". The bottom layer
provides ground for the RF transmission lines.
The transmission lines were designed using a
coplanar waveguide with ground plane model
using a trace width of 0.037", trace gaps of 0.008",
dielectric thickness of 0.059" and metal thickness
designs
of 0.0015".
w ^{J3 provides an optional external DC bias that can}
be applied to the LO input, if there is DC
e _{component to the applied RF input. To use this}
n _{option, transformers T2 and T3 must be carefully}
chosen to allow the use of a non-zero common-
r _{mode level.}
fo _{J9 can be used to enable or disable the part. The}
t _{chip enable/EN is active low.}
o _{De-coupling capacitors are provided on the VDD}
N _{traces. These capacitors should be placed as}
close to the DV_DD pin as possible.
