General Description
The HMC558LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant SMT
package that can be used as an upconverter or
downconverter between 5.5 and 14 GHz. This mixer
is fabricated in a GaAs MESFET process, and
requires no external components or matching cir-
cuitry. The HMC558LC3B 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 HMC558LC3B elim-
inates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.
Electrical Specifications, TA = +25° C, IF= 100 MHz, LO= +15 dBm*
