ZEL-0812LN Coaxial Low Noise Amplifier 800 to 1200 MHz

Category: Electronics, Minicircuits, RF Microwave Devices

Overview

The ZEL-0812LN is a coaxial low noise amplifier designed for operation in the wide frequency band of 800 to 1200 MHz. It showcases a very low noise figure with a maximum of 1.5 dB and is encapsulated in a rugged, shielded case, making it ideal for high-reliability applications such as UHF cellular and PCS/GSM systems. The amplifier is equipped with SMA connectors and is housed in an EEE132 case style.

Key Features and Specifications

The ZEL-0812LN amplifier offers consistent performance with a typical gain of 1.0 dB across the operating bandwidth. Gain flatness is a crucial parameter measured at a maximum of 2.5 dB, ensuring a stable signal across all frequencies. The output power at 1dB compression is specified, along with the output third-order intercept point, providing insights into the amplifier’s linearity and power handling performance.

Other important electrical characteristics include the input and output voltage standing wave ratio (VSWR) ensuring minimal signal reflection and efficient power transfer. The recommended DC supply voltage is accompanied by the supply current specifications, highlighting the amplifier’s power requirements.

The noise figure, a critical aspect of any low noise amplifier, is stated to be a maximum of 1.5 dB at room temperature, with a typical increase to 2 dB at high temperatures of +85°C. Additionally, users are cautioned against operating the amplifier with an open load, as it can potentially cause damage.

Environmental and Physical Specifications

For suitability in a variety of environments, the operational temperature range is detailed from -54°C to 85°C, with a broader storage temperature range of -55°C to 100°C. Maximum ratings are provided to help users understand the limits of DC voltage and input RF power, preventing permanent damage by staying within specified limits.

Physical dimensions in both inches and millimeters are provided on the datasheet, along with an outline drawing, to help with mechanical integration. The amplifier’s lightweight, at 106 grams, is also highlighted.

Performance Data and Warranty

The datasheet includes a series of graphs showing performance data such as gain, directivity, VSWR, noise figure, and output power at 1-dB compression across the specified frequency range. These serve as a visual tool for assessing the amplifier’s performance characteristics.
