BR9643LDZ is a MMIC gain block amplifier die designed using GaAs process which operates between 2GHz~20GHz. The amplifier is powered by a single-supply operation of +5V or +3.3V. At 11GHz, the amplifier typically provides a gain of 15dB, an output P1dB of 16.6dBm, and a noise figure of 2.1dB under the condition of +5V power supply. It has been internally matched to 50 ohms and AC coupled, thereby eliminating the need for external DC blocks and RF port matching. The BR9643LDZ amplifier is ideal for integration into Multi-Chip-Modules (MCMs) due to its small size.
