This PDF file introduces the Rohde & Schwarz PQA100 and PQA200 series of spectrum analyzers, which are high-performance instruments that can be used for a variety of applications, including RF testing, signal analysis, power quality analysis and telecommunications testing. The file provides detailed information on the features and characteristics of these products, including frequency range, sampling rate, resolution and dynamic range.
The document describes the KA22900/D as a monolithic integrated circuit designed for use in AM/FM radios and headphone radios. It functions as a 3V one-chip tuner that includes both an FM stage (RF/IF/AF amp, Quadrature Detector) and an AM stage (RF/IF/AF amp, Detector), along with an MPX stage for stereo decoding.
Key features highlighted include the elimination of external components such as AM detect coils and IF coupling capacitors. The device supports a wide operating voltage range from 1.8V to 7V and offers low distortion levels for both FM and AM signals.
| Operating Voltage Range | 1.8V ~ 7V |
|---|---|
| AM IF Total Harmonic Distortion | 1% (Typ) |
| Operating Temperature Range | -20°C ~ +75°C |
The device supports a wide operating voltage range from 1.8V to 7V.
No, it does not require an AM detect coil as it is a one-chip tuner.
The KA22900/D is available in 24-SDIP-300 and 24-SOP-375 packages.
