Description Absolute MAxiMuM input

rAtings

LTC5548

2GHz to 14GHz Microwave

Mixer with Low IF Frequency

Demonstration circuit 2461A is optimized for evaluation

of the LT C

5548 passive double-balanced mixer with

integrated LO frequency doubler. Its RF port is matched

to 50Ω from 2GHz to 13.6GHz with 9dB return loss, and

the LO port is matched to 50Ω from 1GHz to 12GHz with

10dB return loss. The differential IF port is usable from

DC to 6GHz. The LTC5548 can be used for upconverting

and downconverting applications.

The internal LO doubler can be enabled to allow operation

with a lower frequency LO input signal such as that from

the LTC6945/LTC6946 or LTC6947/LTC6948 family of

frequency synthesizers.

notes on test eQuipMent AnD setup

•High performance signal generators with lowharmonic

outputs should be used for 2-tone measurements.

Otherwise, low pass filters at the signal generator

outputs should be used to suppress harmonics.

•High quality combiners should be used to present

a broadband 50Ω termination on all ports as well

as provide good port-to-port isolation. Adding at-

tenuator pads further improves source isolation and

helps prevent the signal generators from producing

intermodulation products.

•Spectrum analyzers can produce significant internal

distortion products if they are overdriven. Generally,

spectrum analyzers are designed to operate at their

best with about –30dBm to –40dBm at their input. The

spectrum analyzer’s input attenuation setting should

be used to avoid saturating the instrument.

•Set the spectrum analyzer’s input attenuation depend-

ing on the spectrum analyzer used.

•Before performing measurements on the DUT, the

system performance should be evaluated toensure that

a clean input signal is obtained and that the spectrum

analyzer’s internal distortion is minimized.

1. Connect all test equipment as shown in Figure 2.

2. Set the power supply output voltage to 3.3V, and set

the current limit to 200mA.

3. Connect the ground and VCC turrets to the power sup-

ply. BE SURE TO CONNECT THE VCC TURRET BEFORE

THE EN TURRET TO ENSURE THAT THE PART DOES

NOT GET DAMAGED. ALSO, REMOVE POWER FROM

EN TURRET BEFORE REMOVING POWER FROM THE

VCC TURRET.

4. Connect the EN turret to the power supply.

5. Set the LO signal generator to provide a 5560MHz CW

signal at about 0dBm to the demo board’s LO port.

6. Set the RF signal generators to provide one 5799MHz

CW signal and one 5801MHz CW signal. The signals

should be applied to the 2-way combiner. The output

of the combiner should be applied to the demo board’s

RF input port. The two tones should be set to –5dBm

each at the mixer’s RF input port.

7. Setthespectrumanalyzer’scenter frequencyto240MHz

with a span of 10MHz.

8. Perform various measurements

(Conversion Gain, OIP3, LO leakage, etc.)
