HMC495LP3 / 495LP3E

v02.0705

SiGe WIDEBAND DIRECT

MODULATOR RFIC, 250 - 3800 MHz

Typical Applications

Features

The HMC495LP3 / HMC495LP3E is suitable for

various modulation systems:

Wideband RF Frequency Range

High Carrier Suppression: 38 dBc

Very Low Noise Floor: -158 dBm/Hz

Low LO Power: -6 to +6 dBm

• UMTS, GSM or CDMA Basestations

• Fixed Wireless or WLL

• ISM Transceivers, 900 & 2400 MHz

• GMSK, QPSK, QAM, SSB Modulators

Differential or Single Ended LO Input

Single Low Current Supply: +3.3V@ 108 mA

General Description

Functional Diagram

The HMC495LP3 & HMC495LP3E are low noise

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.
