Calterah Raises $140M+ in Series E

🔑 Enhanced Key Takeaways

• •Calterah was founded in 2014 and pioneered the world's first mass-produced 77/79 GHz CMOS mmWave radar sensor chip (Yosemite family) in 2017[1][2][4].
• •The company has shipped over 20 million ICs, collaborates with more than 30 automotive manufacturers worldwide, and equips over 300 car models with its mmWave radar SoCs[5].
• •Calterah holds more than 600 patents and recently verified the world's first 802.15.4ab UWB chip (Dubhe-UWB-SoC series with 2T4R architecture) for demo at CES 2026[5].
• •Product portfolio includes advanced SoCs like Andes CAL77C644/844-AF, Alps-Pro CAL77S344-AE, Rhine CAL60S244-AB AiP, Alps-Mini CAL77S322-AC, and Alps CAL77S244-AE/AB showcased at IAA Mobility 2023[6].

🛠️ Technical Deep Dive

• •Alps 77/79 GHz chip series: up to 4 transmitter channels, 4 receiver channels, highly configurable waveform generator, analog-to-digital converter with up to 50 MSPS sampling rate, hardware-implemented radar algorithms for low power and high performance[2][3].
• •Yosemite: world's first mass-produced 77/79-GHz CMOS mmWave radar transceiver for automotive use[1][2][4].
• •Yellowstone: 60-GHz CMOS mmWave radar transceiver, mass-produced in 2017[2].
• •Dubhe-UWB-SoC: world's first UWB-SoC with 2T4R (two transmit, four receive channels), integrates positioning and radar functions, uses BLE-Assisted-MMS for wireless distance measurement[5].
• •Antenna-in-Package (AiP) technology integrates antenna array within chip package, reducing high-frequency PCB use and accelerating radar module development[1].
