Demonstration circuit 862 is a micropower regulated charge pump DC/DC converter featuring the 60mA output LTC3221 in a 2mm × 2mm DFN package. It comes in three assembly versions, DC862A-A, DC862A-B and DC862A-C, featuring the LTC3221EDC-3.3 (fixed 3.3V output), the LTC3221EDC-5 (fixed 5V output) , and LTC3221EDC (adjustable output set to 3V), respectively. The demo board input voltage range depends on the IC used; for the adjustable output DC862A-C, the input voltage range is 1.8V to 3.8V. The LTC3221's low 8µA no-load quiescent current is even lower than the self-discharging current of many batteries. By employing a constant current to charge the output, the output ripple is low even at high input and light load, and is fairly constant over the full input voltage range.

The HMC1120 is an RMS power detector with an integrated high bandwidth envelope detector. The RMS output is a temperature compensated, monotonic, linear-in-dB representation of real RF signal power, measured over an input sensing range of 70 dB. The envelope detector provides an accurate voltage output which is linearly proportional to the amplitude envelope of the RF input signal for modulation bandwidths up to 150 MHz. The high bandwidth envelope detection of the HMC1120 makes it ideal for detecting broadband and high crest factor RF signals commonly used in GSM, WCDMA, and LTE systems. Additionally, the instantaneous envelope output can be used to create fast, excessive RF power protection, PA linearization, and efficiency enhancing envelope-tracking PA implementations.The HMC1120?s RMS detector integration bandwidth is digitally programmable via input pins SCI1-4 over a range of more than 4 decades. This allows the user to dynamically set the operation bandwidth and also permits the detection of different types of modulations on the same platform.The HMC1120 features an internal op-amp at the RMS output stage, which accommodates slope and intercept adjustments and supports a wide range of applications.Applications Log ?> Root-Mean-Square (RMS) Conversion Tx/Rx Signal Strength Indication (TSSI / RSSI) RF Power Amplifier Efficiency Control Receiver Automatic Gain Control Transmitter Power Control Envelope Tracking PA Linearization
