Overview

The datasheet provides extensive information on the RF Amplifier Model QBH-136, including its high gain and power output capabilities. The amplifier is suitable for operations across various temperatures, with environmental screening options available. Two model configurations are mentioned: the 4 Pin TO-8 Tall (QBH-136) and the Connectorized Housing (QBH-9-136).

Maximum Ratings

The product is designed to operate within a specific range of temperature and power conditions. The maximum ambient operating temperature is between -55°C to +100°C, storage temperature from -65°C to +150°C, and the case temperature is rated at +125°C. The datasheet advises that the DC voltage should not exceed 17 volts. It also details limits on continuous and short-term RF input power, along with maximum peak power constraints.

Specifications

The specifications section covers a broad range of parameters, such as frequency, gain, gain versus temperature, gain flatness, reverse isolation, output power, and several other characteristics at different temperatures (-40°C to +85°C). Important performance indicators include a typical gain of 20.0 dB, gain flatness of maximum 1.0 dB, minimum reverse isolation of -25 dB, VSWR (Voltage Standing Wave Ratio) out of 1.5:1 maximum, and minimum output power of +19 dBm. Additionally, the third and second order intercept points, noise figure, and power consumption are detailed.

Typical Performance Data

This section of the datasheet illustrates typical performance data for the RF Amplifier Model QBH-136 through graphical representations of reverse isolation, gain, noise figure, dB Compression, input/output VSWR, and third-order intermodulation distortion across a frequency range of 100 MHz to 1000 MHz. Each graphic visually corresponds to different operating temperatures: +25°C, +85°C, and -40°C, indicating the product’s stability across various environmental conditions.

Linear S-Parameters Data

The linear S-parameters data is provided for technical analysis, offering information on S11, S21, and S12 parameters at specific frequencies, alongside their corresponding angles and dB values. These S-parameters are essential for engineers to assess the signal reflections and transmission through the amplifier.
