Low Noise MMIC Amplifier, 0.5 to 5 GHz

Product Overview Mini-Circuits TSS-53LNB3+ is a low-noise amplifier offering industry-leading performance over its full fre- quency range from 500 MHz to 5 GHz. It contains internal switching, allowing the user control of the ampli- fier to handle both high and low signal levels by bypassing the LNA in the presence of large signals. The TSS-53LNB3+ utilizes E-PHEMT technology to achieve excellent noise figure performance in a unique cascade configuration enabling the combination of very wide band performance and flat gain. This model comes in a tiny, 3 x 3mm, 12-lead MCLP package. Feature Advantages Ultra-wideband: 500 MHz – 5 GHz Ideal for a wide range of receiver applications including military, commercial wireless, and instrumentation. Very flat gain Ideal for broadband or multi-band applications. Just one, cost-efficient model required for multiple frequency usage. Minimal external matching components required. 15 dB return loss typ. Minimizes the need for external matching networks, simplifying circuit designs, and enabling the amplifier to operate over multiple bands in a single application circuit. Internal bypass switch feature Unique design handles low to high signal levels with minimal noise distortion. Built-in DC blocking cap at RF-Out port & separate pads for RF-Out & Vdd Simplifies biasing eliminates need for Bias-Tee at output. Compact size: 3 x 3 x 0.9 mm Saves space in dense system layouts. Low inductance, repeatable transitions, and excellent thermal contact.


Very wideband, 500 MHz – 5 GHz • Ultra-flat gain, ±0.7 dB from 700 to 2100 MHz • Low NF over entire frequency band, 1.5 dB typ.
