Applications Notes
The ZL40000 is a wide band RF signal conditioning and distribution circuit that can be used in many applications.
The device has excellent signal handling performance and provides > 40 dB of AGC range over the full operating
BW of DC to 2GHz.
The device excellent dynamic performance and wide bandwidth make the device ideally suited to providing a
separate buffered RF multi carrier signal to multiple tuner applications such as can be found in next generation Set
Top Boxes, VCRs, DVDs and TVs for Digital Terrestrial, Cable and Satellite.
The device will also satisfy Analogue Terrestrial, Cable and Satellite requirements up to -35dBm / Ch in 130 Carrier
Composite signals from 50MHz to 850 MHz with 6MHz channel spacing.
The very high signal handling RF AGC stage makes the ZL40000 suitable for use in all wide dynamic range receiver
systems operating in the 1MHz to 2GHz band.
The ZL40000 has excellent RF AGC performance providing > 40dB AGC range over the full DC to 2GHz operating
range. The RF AGC range exceeds 60dBC from DC to 500MHz.
Both the excellent RF AGC range and the excellent Multi Carrier performance are achieved as a result of the
balanced nature of the circuit. The ZL40000 can be operated both single ended or differential at both the input and
the output.
The performance achieved with the output signal used differential, increases the RF isolation and adds 20dB
improvement above that achieved single ended. It also greatly reduces the second order distortion and inter
modulation present at the output.
The best performance is achieved when all output ports are connected to balanced loads and if a particular channel
is to be used single ended output, the unused output should be terminated with a matching load.
The excellent RF range and high BW AGC control port makes the ZL40000 suitable for applications in which fast
level control or RF Signal Switching is required such as may be found in Instrumentation.
The RF AGC attenuator can be switched through 60dB of AGC range typically 15nS.
A pair of ZL4000 with cross coupled outputs and a broad band quadrature phase shift unit can be used to build a
broad band RF phase rotator that could be used in Agile Active Antenna Arrays for Transmitters with fast beam
steering.
