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.
