UMS CHA1077A-98F/00 is a W-band monolithic third-order low-noise amplifier (LNA) produced by United Monolithic Semiconductors (UMS), mainly targeted at 76–77 GHz vehicle-mounted radars, millimeter-wave communications, and high-frequency detection instruments. The key indicators are as follows:

　　Frequency range: 76–77 GHz

　　Small-signal gain: 11–19 dB (typical 15 dB)

　　Noise figure: 4.5–6.5 dB (typical 4.5 dB)

　　1 dB compression point output power: 9 dBm

　　The chip is internally self-biased and can be externally connected with a resistor (approximately 2 kΩ) to balance between high gain and low noise

　　Process: 0.15 µm P-HEMT, air bridge + through hole, military-grade temperature range from −40 ℃ to +85 ℃

　　Package: Bare chip (Chip), compatible with automatic soldering
