General Description
The HMC557LC4 is a general purpose double
balanced mixer in a leadless RoHS compliant
SMT package that can be used as an upconverter
or downconverter between 2.5 and 7 GHz. This
mixer is fabricated in a GaAs MESFET process,
and requires no external components or matching
circuitry. The HMC557LC4 provides excellent LO to
RF and LO to IF isolation due to optimized balun
structures and operates with LO drive levels as low
as +9 dBm. The RoHS compliant HMC557LC4
eliminates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.
Electrical Specifications, T_A = +25° C, IF= 100 MHz, LO= +15 dBm*
