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.

FEATUREs
   Very Low Noise Floor, -161 dBm/Hz
   Very High Linearity, +22 dBm OIP3
   High Output Power, +9 dBm Output P1dB
   High Modulation Accuracy
   DC – 700 MHz Baseband Input

Typical Applications
The HMC497LP4 / HMC497LP4E is suitable for
various modulation systems:
• UMTS, GSM or CDMA Basestations
• Fixed Wireless or WLL
• ISM Transceivers, 900 & 2400 MHz
• GMSK, QPSK, QAM, SSB Modulators
