HMC495LP3 / 495LP3E v02.0705 SiGe WIDEBAND DIRECT MODULATOR RFIC, 250 - 3800 MHz Typical Applications Features The HMC495LP3 / HMC495LP3E is suitable for Wideband RF Frequency Range various modulation systems: High Carrier Suppression: 38 dBc UMTS, GSM or CDMA Basestations Very Low Noise Floor: -158 dBm/Hz Fixed Wireless or WLL Low LO Power: -6 to +6 dBm ISM Transceivers, 900 & 2400 MHz Differential or Single Ended LO Input GMSK, QPSK, QAM, SSB Modulators Single Low Current Supply: +3.3V 108 mA General Description Functional Diagram The HMC495LP3 & HMC495LP3E are low noise 10 Wideband Direct Quadrature Modulator RFICs which are ideal for digital modulation applications from 250 - 3800 MHz including Cellular/3G, Broadband Wireless Access & ISM circuits. Housed in a compact 3x3 mm (LP3) SMT QFN package, the RFIC requires minimal external components & provides a low cost alternative to more complicated double upconversion architec- tures. The RF output port is single-ended and matched to 50 Ohms with no external components. The LO re- quires -6 to +6 dBm and can be driven in either dif- ferential or single-ended mode while the Baseband in- puts will support modulation inputs from DC - 250 MHz typical. This device is optimized for a supply voltage of +3.3V 108 mA and will provide stable performance over a +3V to +3.6V range. Electrical Specifi cations, 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.
