Functional Diagram
General Description
The HMC551LP4 & HMC551LP4E are high linear-
ity, double balanced Converter ICs that operate from
0.8 to 1.2 GHz and deliver a +27 dBm input third order
intercept point. The LO amplifier output and high
dynamic range mixer input are positioned so that an
external LO filter can be placed in series between
them. The converter provides 27 dB of LO to RF isola-
tion and is ideal for upconverter and downconverter
applications. The IC operates from a single +5V supply
consuming 62 mA of current and accepts a LO drive
level of -4 to +4 dBm. The design requires no external
baluns and supports IF frequencies between DC and
300 MHz. The HMC551LP4 & HMC551LP4E are pin for
pin compatible with the HMC552LP4 & HMC552LP4E
which operate from 1.6 to 3.0 GHz.
Electrical Specifications, T_A = +25° C, LO = 0 dBm, Vcc = +5V, IF = 100 MHz*
