Product Description
SPM-1045
The Sirenza SPM-1045 is a passive mixer designed for
systems that require high linearity up- and down-conver-
sion. It employs proprietary silicon FETs with proven reli-
able core-and-wire baluns. It operates efficiently over a
wide range of Local Oscillator powers, with input third
order intercept remaining approximately 15-20 dB above
LO power. This product is packaged in a standard surface
mount module for excellent RF performance.

Operation of this device beyond any one of these limits may

device voltage and current must not exceed the maximum oper-
ating values specified in the table on page one.
The SPM-1045 mixer is a MOSFET based high performance mixer designed for high linearity frequency conversion in the
US cellular band. This mixer features a wide latitude in LO power requirements. Conversion loss remains virtually constant
between 10dBm and 17dBm of LO power. Third Order Intercept is approximately proportional to the LO drive. This means
that this mixer can be used to replace a wide variety of mixers requiring a variety of LO powers. The mixer uses baluns on
all three ports, so each port presents a DC short.
The graphs on the following pages illustrate the performance of the SPM-1045 over a variety of operating conditions. In
order to duplicate these performance tests, the following precautions should be observed:
-The mixer should be presented with good return losses at all ports by using isolators or attenuators. This is especially true
of the LO port, because of the poor return loss of this port. If ripple is seen in a frequency sweep, it is likely due to reflections
caused by poor VSWR in a cable leading up to the device.
-The presence of harmonics in the LO can cause changes in TOI.
-Be aware that signals of many different frequencies exist at the output of the mixer, and any one can potentially cause the
spectrum analyzer to generate intermod.
-When measuring TOI, make sure the two generators supplying the RF signal are not interacting, causing intermod them-
selves.

These graphs show mixer conversion loss vs. frequency, with both low-side LO excitation (LO frequency below the RF fre-
quency) and high side excitation (LO frequency above the RF frequency). Operation both as a down-converter and an up-
converter is shown, with LO powers of 10, 14, and 17dBm. In all cases, the IF frequency is 100MHz.

These graphs show mixer Third Order Intercept (TOI) vs. frequency referenced to the input of the mixer (that is, referenced
to the RF port in the case off a down-converter, or the IF port in the case of an up-converter), with both low-side LO excita-
tion (LO frequency below the RF frequency) and high side excitation (LO frequency above the RF frequency). Operation
both as a down-converter and an up-converter is shown, with LO powers of 10, 14, and 17dBm. In all cases, the IF fre-
quency is 100MHz. The RF power used in measuring third order intercept is +0dBm, except in cases where TOI exceeds
30dBm, in which case input power is increased to make the intermod tones visible above the noise floor.

The contour graphs show mixer input TOI and conversion loss over a variety of RF and LO frequencies. These contour
graphs can be used to assess the suitability of these mixers over a variety of frequencies of operation. Note that constant IF
frequency curves can be overlaid as diagonal lines. Also shown are graphs of TOI and insertion loss vs. temperature.
These curves were measured down-converter mode, with 750MHz LO, 850MHz RF and 14dBm LO power.

The isolation graph shows port isolation with a 750MHz LO at 17dB.
Half IF response is measured by applying RF signals (10dBm amplitude) 50MHz above or below the LO, and measuring
the level of the undesired IF component at 100MHz.
