Functional Diagram
General Description
The HMC258LC3B is a 14.5 - 19.5 GHz surface
mount sub-harmonically pumped (x2) MMIC mixer
with an integrated LO amplifier in a SMT leadless
ceramic package. At 45 dB the 2LO to RF isolation
eliminates the need for additional filtering. The LO
amplifier is a single bias (+5V) two stage design with
only 0 dBm drive requirement. The HMC258LC3B
requires no external matching components, making it
ideal for integrated subsystem applications. Utilizing
the HMC258LC3B eliminates the need for wirebonding, thereby providing a consistent connection
interface for the customer.

IF
IF Port. This pin is DC coupled and should be DC blocked
externally using a series capacitor whose value has been
chosen to pass the necessary IF frequency range. Any applied
DC voltage to this pin will result in die non-function and
possible die failure.

Vdd
Power Supply for the LO Amplifier. An external RF bypass
capacitor of 100 - 330 pF is required as close to the package
as possible.

[2] Circuit Board Material: Rogers 4350
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used
to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
