• Manufacturer Part Number: ADL5802_09
• Description: Dual Channel, High IP3, 100 MHz to 6 GHz Active Mixer
• Manufacturer: AD [Analog Devices]

APPLICATIONS INFORMATION
BASIC CONNECTIONS
The ADL5802 features dual channel mixers with a common
local oscillator (LO). The mixer is designed to translate between
radio frequencies (RF) and intermediate frequencies (IF). For
both upconversion and downconversion applications, RF1+
(Pin 23), RF1− (Pin 22), RF2+ (Pin 20), and RF2− (Pin 19)
must be configured as the input interfaces. OP1+ (Pin 3), OP1−
(Pin 4), OP2+ (Pin 16), and OP2− (Pin 15) must be configured
as the output interfaces. Figure 68 illustrates the basic connections
for ADL5802 operation.

RF AND LO PORTS
The RF and LO input ports are designed for differential input
impedance of approximately 50 Ω. Figure 69 and Figure 70
illustrate the RF and LO interfaces, respectively. It is recommended
that each of the RF and LO differential ports be driven through a
balun for optimum performance. It is also necessary to ac-
couple both RF and LO ports with the proper size capacitors.
Table 4 lists the recommended components for various RF
frequency bands. The characterization data is available in the
Typical Performance Characteristics section.
