HMC258LC3B
v03.0414
GaAs MMIC SUB-HARMONIC
SMT MIXER, 14.5 - 19.5 GHz
General Description
Features
Functional Diagram
The HMC258LC3B is a 14.5 - 19.5 GHz surface
mount sub-harmonically pumped (x2) MMIC mixer
with an integrated LO amplier in a SMT leadless
ceramic package. At 45 dB the 2LO to RF isolation
eliminates the need for additional ltering. The LO
amplier 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 wire-
bonding, thereby providing a consistent connection
interface for the customer.
Integrated LO Amplier: 0 dBm Input
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: >45 dB
