12-Bit Digital Pre-Distortion

Receiver Subsystem

FEATURES

DESCRIPTION

The LTM^®9003 is a 12-bit digital pre-distortion receiver

subsystem for the transmit path of cellular basestations.

Utilizing an integrated system in a package (SiP) tech-nol-

ogy, it includes a downconverting mixer, wideband ﬁlter

andanalog-to-digitalconverter(ADC).Thesystemistuned

for an intermediate frequency (IF) of 184MHz and a signal

bandwidth of up to 125MHz. The 12-bit ADC samples at

rates up to 250Msps. Contact Linear Technology regard-

ing customization.

Fully Integrated Receiver Subsystem for Digital

Pre-Distortion Applications

Down-Converting Mixer with Wide RF Frequency

Range: 400MHz to 3.8GHz

125MHz Wide Bandpass Filter, <0.5dB Passband

Ripple

Low Power ADC with Up to 12-Bit Resolution,

250Msps Sample Rate

–145.5dBm/Hz Input Noise Floor, 25.8dBm IIP3

1.5W Total Power Consumption

The high signal level downconverting active mixer is opti-

mized for high linearity, wide dynamic range IF sampling

applications. It includes a differential LO buffer ampliﬁer

driving a double-balanced mixer. Broadband, integrated

transformers on the RF and LO inputs provide single

ended 50Ω interfaces. The RF and LO inputs are internally

matched to 50Ω from 1.1GHz to 1.8GHz.

50Ω Single-Ended RF and LO Ports

Internal Bypass Capacitance, No External

Components

ADC Clock Duty Cycle Stabilizer

11.25mm × 15mm LGA package

APPLICATIONS

The CLK input controls converter operation and may be

drivendifferentiallyorsingle-ended.Anoptionalclockduty

cycle stabilizer allows high performance at full speed for

a wide range of clock duty cycles.
