Introduction In the RF signal chain (Figure 1) of communication infrastructure equipment, radar, RFID readers, measurement and control, consumer electronics, medical equipment, amplifiers (low noise amplifier LNA, intermediate frequency amplifier IFA, driver amplifier and gain block) are important device. ADI's latest offering covers the entire RF signal chain with 12 amplifiers. These amplifiers are combined with power detectors, modulators, demodulators, and synthesizers for complete signal chain solutions. ADI's new family of four high-performance RF amplifiers includes LNAs (low noise amplifiers), IFAs (intermediate frequency amplifiers), driver amplifiers and RF gain blocks. As the first amplifier in the receive chain, the low noise amplifier (LNA) is an important part of defining the performance of the overall system and must be able to successfully amplify very low level signals without significantly increasing noise. ADI's LNA_ADL5521 and AD5523 work at 400MHz~4GHz, with the best gain (15dB for ADL5521, 17.5dB for ADL5523), low noise figure (0.8dBNF for ADL5521, 1.1dBNF for ADL5523), high output third-order intermodulation carrier point, low power consumption, internal active bias circuitry, and requires minimal external tuning components. Intermediate Frequency Amplifiers Analog Devices' Intermediate Frequency Amplifiers (IFA) ADL553x series (ADL5530, ADL5531, ADL5532, ADL5533 (75Ω), ADL5534 (dual channel)) is specially designed to support the most common IF applications such as 70.140.190.240 and 380MHz. The new IFA provides a high linearity of 41dBm, and its noise figure remains at 2.5dB for the best signal dynamic range. In addition, it also has built-in on-chip bias circuits and supports 1KVClass1CESD. Driver Amplifiers The ADL532x driver amplifier family provides the highest linearity for a given output power, enabling low distortion, high output drive directly for power amplifier stages. The ADL5320 has an operating bandwidth of 400MHz to 2.7GHz, provides 42dBm output linearity and 26dBm output compression point, and consumes only 104mA of current. The ADL5322 and ADL5323 operate in the 700MHz~4GHz and 1.7GHz~2.4GHz frequency bands, respectively, with 45dBm output IP3 linearity and 28dBm compression point, and they are internally matched to eliminate less than 10 external components. Both amplifiers offer excellent adjacent channel power ratios for CDMA and W-CDMA applications (at output powers above +10dBm, the ADL5323 provides an adjacent channel leakage ratio ACPR of better than 70dBc). Gain Blocks The ADS5541 and ADL5542 are broadband gain blocks operating from low frequencies to 6GHz. Both modules have internal matching 50ΩImpedance, built-in bias circuit. ADL5541 provides 15dB gain, 40dBm output linearity, ADL5542 provides 20dB gain, 40dBm output linearity. Both broadband gain blocks are fully electrostatic discharge (ESD) protected and available in small lead LFCSP packages. Conclusion The RF amplifiers described in this article support higher performance and wider bandwidth applications in next-generation broadband access systems without sacrificing cost, size, or power consumption. Each RF amplifier family offers the highest linearity gain, noise figure and frequency range performance, with high ESD level design and excellent product consistency.
