SPURIOUS PERFORMANCE
Mixer spurious products are measured in dBc from the IF output power level. Spur values are (M × RF) − (N × LO).
Lower sideband selected, IF = 100 MHz, RF frequency = 8.1 GHz, RF input power = −10 dBm, LO frequency = 8.0 GHz, LO drive = 15 dBm.

THEORY OF OPERATION
The HMC558A 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 GHz and 14 GHz. This
mixer is fabricated in a GaAs MESFET process, and requires no
external components or matching circuitry. The HMC558A
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 HMC558A eliminates the need for
wire bonding, and is compatible with high volume surface mount
manufacturing techniques.

EVALUATION BOARD INFORMATION
The circuit board used in an application must use RF circuit
design techniques. Signal lines must have 50 Ω impedance, and
the package ground leads and exposed pad must be connected
directly to the ground plane, similarly to that shown in Figure 35.
Use a sufficient number of via holes to connect the top and
bottom ground planes. The evaluation circuit board shown in
Figure 35 is available from Analog Devices, Inc., upon request.
