General Description
Functional Diagram
The
HMC277MS8
&
HMC277MS8E
are
8
general purpose single balanced mixers in
lead plastic surface mount Mini Small Outline
Packages (MSOP). This passive MMIC mixer is
constructedofGaAsSchottkydiodesandanovelplanar
transformer balun on the chip. The HMC277MS8(E)
requiresnoexternalmatchingcomponents, andisideal
for upconverter and downconverter applications.The
RF port is balanced via the MMIC balun while the LO
port is connected directly to the diodes. This product is
pin for pin compatible with the HMC272MS8(E) which
operates from 1.7 to 3.0 GHz.
Electrical Specifications, TA = +25° C, LO = +13 dBm, IF = 100 MHz*
