FeaTures

DescripTion

The LTC^®6431-15 is a gain-block amplifier with excellent

linearity at frequencies beyond 1000MHz and with low

associated output noise.

20MHz to 1700MHz Bandwidth

15.5dB Power Gain

47dBm OIP3 at 240MHz into a 50Ω Load

NF = 3.33dB at 240MHz

The unique combination of high linearity, low noise and

low power dissipation make this an ideal candidate for

many signal-chain applications. The LTC6431-15 is easy

to use, requiring a minimum of external components. It is

internally input/output matched to 50Ω and it draws only

90mA from a single 5V supply.

1nV/√Hz Total Input Noise

S11 < –15dB Up to 1.2GHz

S22 < –15dB Up to 1.2GHz

>2V Linear Output Swing

P-P

P1dB = 20.6dBm

DC Power = 450mW

50Ω Single-Ended Operation

On-chip bias and temperature compensation maintain

performance over environmental changes.

Insensitive to V Variation

A-Grade 100% OIP3 Tested at 240MHz

Input/Output Internally Matched to 50Ω

Single 5V Supply

The LTC6431-15 uses a high performance SiGe BiCMOS

process for excellent repeatability compared with similar

GaAsamplifiers.AllA-gradeLTC6431-15devicesaretested

and guaranteed for OIP3 at 240MHz. The LTC6431-15 is

housed in a 4mm × 4mm 24-lead QFN package with an

exposedpadforthermalmanagementandlowinductance.
