SPURIOUS AND HARMONICS PERFORMANCE
Mixer spurious products are measured in dBc from the IF
output power level. N/A means not applicable.
Downconverter M × N Spurious Outputs
Spur values are (M × RF) − (N × LO).
RF = 6.1GHz at −10 dBm , LO = 6 GHz at 15 dBm.

THEORY OF OPERATION
The HMC129ALC4 is a general-purpose, double-balanced
mixer that can be used as an upconverter or a downconverter
from 4 GHz to 8 GHz.
When used as a downconverter, the HMC129ALC4 downconverts
radio frequencies (RF) between 4 GHz and 8 GHz to intermediate
frequencies (IF) between dc and 3 GHz.
When used as an upconverter, the mixer upconverts intermediate
frequencies between dc and 3 GHz to radio frequencies between
4 GHz and 8 GHz.

APPLICATIONS INFORMATION
TYPICAL APPLICATION CIRCUIT
Figure 39 shows the typical application circuit for the
HMC129ALC4. The HMC129ALC4 is a passive device
and does not require any external components. The LO pin
is internally ac-coupled. The RF and IF pins are internally
dc-coupled. When IF operation to dc is not required, using an
external series capacitor is recommended, of a value chosen to
pass the necessary IF frequency range. When IF operation to dc
is required, do not exceed the IF source and sink current rating
specified in the Absolute Maximum Ratings section.

EVALUATION PCB INFORMATION
Use RF circuit design techniques for the circuit board used in
the application. Ensure that signal lines have 50 Ω impedance,
and connect the package ground leads and the exposed pad
directly to the ground plane (see Figure 40). Use a sufficient
number of via holes to connect the top and bottom ground
planes. The evaluation circuit board shown in Figure 40 is
available from Analog Devices, Inc., upon request.
