Description
AI
The HMC495LP3(E) is a low noise Wideband Direct Quadrature Modulator RFIC which is 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 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 - 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.ApplicationsUMTS, GSM or CDMA BasestationsFixed Wireless or WLLISM Transceivers, 900 & 2400 MHzGMSK, QPSK, QAM, SSB Modulators
