FTO-40000-K1

nnnn

Overview:

nnnn

The FTO-40000-K1 provides a low-noise source at 40 GHz and

nnnn

is commonly used as a key component in mm-wave communi-

nnnn

cations, defense instrumentation, and optical-communication

nnnn

systems.

nnnn

This low-jitter source uses a high-performance, low-noise silicon

nnnn

bi-polar junction transistor (Si BJT) in conjunction with a high-Q

nnnn

planar transmission line to realize an X-band, low-noise oscillator.

nnnn

A GaAs PHEMT MMIC frequency multiplier is used to generate a

nnnn

40 GHz signal. Finally the

nnnn

signal is passed through a

nnnn

band-pass filter and me-

nnnn

dium power amplifier before

nnnn

coupling to the output port.

nnnn

Features:

nnnn

• Operating frequency 40 GHz

nnnn

• Output power 18 dBm typical

nnnn

• Phase noise < -95 dBc/Hc @ 100 kHz.

nnnn

• Low power consumption
