Abstract
Jezgra ovog rada su pojačalo snage HMC441LP3 i digitalno upravljani atenuator HMC424ALP3E tvrtke Hittite Microwave Corporation. Napajanje je izvedeno korištenjem prekidačkih istosmjernih pretvornika i linearnih naponskih regulatora. 8-bitni mikrokontroler se koristi za upravljanje razinom atenuacije, a logičkim inverterom se signali prilagođavaju digitalnim ulazima atenuatora. Rezultati mjerenja su pokazali da u zadanom frekvencijskom rasponu pojačalo snage radi očekivano, a mjerenja atenuatora odstupaju od specifikacija za frekvencije veće od 4 GHz. U kaskadnom spoju pojačala snage i atenuatora javlja se valovitost prijenosne karakteristike od 3 dB.
Abstract (english)
The core of this work is the HMC441LP3 power amplifier and the digitally controlled HMT424ALP3E attenuator of Hittite Microwave Corporation. The power supply is designed with switching DC – DC converters and linear voltage regulators. The 8-bit microcontroller is used to control the attenuation level, and the logic inverter adjusts the signals to the digital inputs of the attenuator. The measurement results showed that in the given frequency range the power amplifier is working expected and the attenuator measurements deviate from the specifications for frequencies greater than 4 GHz. In the cascade of power amplifiers and attenuators, the waviness of the transfer characteristic is 3 dB.
