Specs

Frequency Range

The TQL9092 covers a wide frequency range, making it suitable for many RF applications. It operates from 600 MHz up to 4.2 GHz. This broad range allows engineers to use the amplifier in both lower and higher frequency systems. The table below compares the TQL9092 with a similar amplifier, the TQL9093:

Amplifier	Frequency Range	Gain (dB)	Noise Figure (dB)
TQL9092	600 MHz–4.2 GHz	22.6	0.53
TQL9093	600 MHz–4.2 GHz	19.9	0.67

The TQL9092 stands out by offering higher gain and a lower noise figure than the TQL9093, even though both support the same frequency band. This advantage makes the TQL9092 a better choice for sensitive RF designs.

Gain and Flatness

Engineers value consistent gain across a wide frequency range. The TQL9092 delivers a typical gain of 22.6 dB. It maintains a gain flatness of about 2 dB peak-to-peak between 1.5 and 3.6 GHz. This means the amplifier boosts signals evenly, which helps prevent distortion and ensures reliable performance. The stable gain profile supports applications that require uniform amplification, such as wireless base stations and distributed antenna systems.

Noise Figure

A low noise figure is critical in RF design. The TQL9092 achieves a noise figure of around 0.6 dB at 2.6 GHz. This low value means the amplifier adds very little noise to the signal. As a result, systems using the TQL9092 can detect weaker signals and maintain better signal quality. High linearity and low noise together help reduce signal distortion and improve overall system performance.

Tip: Choosing an amplifier with a low noise figure and high linearity, like the TQL9092, can greatly improve the sensitivity and clarity of RF systems.

Power and Package

The TQL9092 operates with a single positive supply voltage between 3.3 V and 5 V. It draws about 65 to 67 mA of current during normal operation. The device comes in a compact 2 x 2 mm DFN-8-EP surface-mount package. This small footprint allows designers to save space on crowded circuit boards. The package also supports easy integration into automated assembly lines, which is important for large-scale production.

The combination of wide frequency coverage, high gain, flat response, low noise, and efficient power use makes the TQL9092 a strong candidate for demanding RF applications.

Performance Benefits

RF designers often look for amplifiers that can boost signals without adding unwanted noise or distortion. The TQL9092 delivers on these needs with its ultra-low noise figure and high gain. These features help maintain the quality of weak signals, making them easier to process in receiver chains. The amplifier’s flat gain response ensures that signals across a wide frequency range receive consistent amplification. This consistency reduces the risk of signal distortion, which is important for reliable communication.

The following table highlights how the TQL9092 improves signal-to-noise ratio (SNR) in RF systems:

Parameter	TQL9092 Value	Impact on SNR Improvement
Noise Figure	0.53 dB	Ultra-low noise figure reduces noise, improving SNR
Gain	22.6 dB	High gain amplifies signal, enhancing SNR in receiver chains

A low noise figure means the amplifier adds very little noise to the original signal. High gain ensures that even weak signals become strong enough for further processing. Together, these features help systems detect and use signals that might otherwise be lost. The TQL9092’s flat-gain and high-linearity design also reduce distortion, which keeps the signal clear and accurate.

Note: Consistent amplification and low noise are key for high-quality RF communication. The TQL9092 helps achieve both, making it a strong choice for demanding designs.

Use Cases

Engineers use the TQL9092 in many commercial and industrial RF systems. Its robust design and reliable performance make it suitable for harsh environments and critical applications. Some of the most common use cases include:

Outdoor 4G/LTE micro base-stations for industrial networks
Signal extension amplifiers in distributed antenna systems
Wireless infrastructure for mobile and defense communications
Systems that require operation in extreme temperatures and weather conditions

For example, the Ukama project uses this amplifier in its Tower Node and Amplifier Unit. These devices support up to 128 active connections and operate in outdoor industrial settings. They feature wide temperature ratings and weatherproof enclosures, making them ideal for remote or rugged locations. The TQL9092’s low power consumption also supports solar-powered deployments, which are common in modern industrial networks.

RF designers choose this amplifier when they need reliable signal amplification, low noise, and strong performance in challenging environments. Its ability to maintain signal quality helps ensure stable and clear communication, even in the most demanding scenarios.

Comparison

Competing LNAs

Engineers often compare low noise amplifiers (LNAs) by looking at three main factors: gain flatness, noise figure, and linearity. Many popular LNAs, such as the Mini-Circuits PMA2-33LN+ and Analog Devices HMC8410, serve similar markets. These amplifiers offer good performance, but each has its own strengths and weaknesses.

LNA Model	Frequency Range	Gain (dB)	Noise Figure (dB)	OIP3 (dBm)	Gain Flatness (dB)
Mini-Circuits PMA2-33LN+	50–3000 MHz	21	0.5	36	±1.5
Analog Devices HMC8410	0.01–8 GHz	15	1.2	35	±2.0
Qorvo TQL9092	0.6–4.2 GHz	22.6	0.6	39.5	±1.0

Note: Gain flatness shows how much the gain changes across the frequency range. A lower value means more consistent amplification.

Some amplifiers provide lower noise figures, but they may not keep gain as flat across wide frequency bands. Others offer high linearity but sacrifice noise performance. Designers must balance these factors when choosing an LNA.

Unique Value

The TQL9092 stands out because it combines high gain, excellent gain flatness, and strong linearity in a small package. Its gain stays almost the same across a wide frequency range. This helps keep signals clear and strong. The amplifier also handles high input power and works well in tough environments.

Key advantages include:

Consistent gain for reliable signal quality
Ultra-low noise for better sensitivity
High linearity for minimal distortion
Compact size for easy integration
