HMC497LP4 / 497LP4E v02.0506 SiGe WIDEBAND DIRECT MODULATOR RFIC, 100 - 4000 MHz Typical Applications Features The HMC497LP4 / HMC497LP4E is suitable for various modulation systems: Very Low Noise Floor, -161 dBm/Hz • UMTS, GSM or CDMA Basestations High Output Power, +9 dBm Output P1dB • Fixed Wireless or WLL High Modulation Accuracy • ISM Transceivers, 900 & 2400 MHz DC – 700 MHz Baseband Input Very High Linearity, +22 dBm OIP3 • GMSK, QPSK, QAM, SSB Modulators 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. MODULATORS - SMT 9 Electrical Specifications, See Test Conditions on following page herein.

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.
