v00.0409 HMC795LP5E SiGe Wideband Direct Quadrature Modulator w/ vga, 50 - 2800 MHz modulators - direct quadrature - SMT 10 10 - 1 Typical Applications The HMC795LP5E is ideal for: UMTS, GSM or CDMA Basestations Fixed Wireless or WLL ISM Transceivers, 900 & 2400 MHz GMSK, QPSK, QAM, SSB Modulators Cellular/3G and WiMAX/4G Microwave IFs Features High Linearity OIP3: + 22 dBm High Output Power: +10 dBm Output P1dB High Carrier Suppression: 55 dBc High Sideband Suppression: 53 dBc Read/Write Serial Port Interface (SPI) SPI & 6-bit parallel port programmable 32 dB Gain Control DC - 440 MHz Baseband Input 32 Lead 5x5 mm QFN Package: 25 mm2 Functional Diagram General Description The HMC795LP5E is a variable gain, direct quadrature modulator ideal for digital modulation applications from 50 - 2800 MHz including: Cellular/3G, Broadband Wireless Access and ISM circuits. Housed in a compact 5x5mm (LP5) SMT QFN package, the modulator offers a high level of integration, exceptionally low carrier feedthrough, and a low cost alternative to more complicated double upconversion architectures. The LO requires -9 to +3 dBm and can be driven in either differential or single-ended mode. The baseband inputs will support modulation inputs from DC - 440 MHz. The differential RF output port is driven by a 6 bit digital controlled variable gain amplifier to nominally provide up to 32 dB of very linear gain control in 0.5 dB steps. The low carrier suppression is maintained over th...
