The HMC697LP4(E) is a low noise, high linearity Direct
Quadrature Modulator RFIC which is ideal for digital
modulation applications from 0.2 to 4.0 GHz including;
Cellular/3G, WiMAX/4G, 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. This device is optimized for a +5V
supply, and offers improved carrier feedthrough and
sideband suppression characteristics.

Sideband & Carrier Feedthrough Uncalibrated
Test Conditions: Unless Otherwise Specied, the Following Test Conditions Were Used
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.
Interfacing the HMC697LP4(E) with D/A Converters
The HMC697LP4(E) wideband I/Q modulator is suitable to interface with high-speed D/A converters (DAC) to transmit
complex modulation schemes. Please refer to the Product Application Note titled “Interfacing the HMC697LP4(E) with
D/A Converters” for further information.

Evaluation PCB
The circuit board used in the 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.
