Functional Diagram
General Description
The HMC497LP4 & HMC497LP4E are low noisehigh
linearity Direct Quadrature Modulator RFICs which
are ideal for digital modulation applications from
100 - 4000 MHz including; Cellular/3G, Broadband
Wireless Access & ISM circuits. Housed in a compact
4x4 mm (LP4) SMT QFN package, the RFIC requires
minimal external components & provides a low cost
alternative to more complicated double upconversion
architectures. The RF output port is single-ended
and matched to 50 Ohms with no external components.
The LO requires -6 to +6 dBm and can be driven in
either differential or single-ended mode while the
baseband inputs will support modulation inputs from
DC - 700 MHz typical. This device is optimized for
a supply voltage of +4.5V to +5.5V and consumes
170 mA @ +5.0V supply.

Calibrated vs. Uncalibrated Test Results
During the Uncalibrated Sideband and Carrier Suppression tests, care is taken to ensure that the I/Q signal paths from
the Vector Signal Generator (VSG) to the Device Under Test (DUT) are equal. The “Uncalibrated, +25 °C” Sideband
and Carrier Suppression plots were measured at room temperature, while the “Uncalibrated, over Temperature”
Sideband and Carrier Suppression plots represent the worst case uncalibrated suppression levels measured at T=
-40 °C, +25 °C, and +85 °C.
The “Calibrated, + 25 °C” Sideband Suppression data was plotted after a manual adjustment of the I/Q amplitude
balance and I/Q phase offset (skew) at +25 °C, and at each LO input power level. The +25 °C adjustment settings
were held constant during tests over temperature. The “Calibrated, over Temperature” plots represent the worst case
calibrated Sideband Suppression levels at T= -40 °C, +25 °C, and +85 °C.
The “Calibrated, +25 °C” Carrier Suppression data was plotted after a manual adjustment of the Ip/In & Qp/Qn DC
offsets at +25 °C, and at each LO input power level. The +25 °C adjustment settings were held constant during tests
over temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier Suppression levels
measured at T= -40 °C, +25 °C, and +85 °C.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A sufficient number of VIA holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
