Product details
Overview
MC33MR2001R2VKR2 from NXP Semiconductors is a 76–77 GHz three-channel RF receiver IC for automotive radar front-ends, featuring 38 GHz LO input, 23–60 dB programmable conversion gain, 14 dB typical SSB noise figure, and differential IF outputs at up to 5 MHz bandwidth. It operates from a 3.3 V ±5% supply with 242 mA typical current draw and integrates on-chip baseband filtering, saturation detection, and SPI-controlled channel enable/disable.
For engineers reviewing the MC33MR2001R2VKR2 datasheet, MC33MR2001R2VKR2 pinout, MC33MR2001R2VKR2 application, or MC33MR2001R2VKR2 equivalent, this page delivers verified technical context, validated pin functions, real-world ADAS radar use cases, and two confirmed alternative receivers for LRR/MRR/SRR system design.
Technical Context
The MC33MR2001R2VKR2 implements a direct-conversion receiver architecture with dual-stage variable-gain amplifiers (VGA), high-pass and low-pass baseband filters, and integrated saturation detectors per channel. Its RF inputs accept 76–77 GHz signals while driven by a 38–38.5 GHz single-ended LO, enabling heterodyne downconversion to DC-coupled differential IF outputs.
SPI control (up to 10 MHz) manages channel enable/disable, gain settings, test modes, and sensor readout via 6-bit address space. External bias resistors (RP/RN) set temperature sensor slope and reference voltage; all three RF inputs (RX1–RX3) and IF pairs (IF1/IF1x through IF3/IF3x) are fully independent and calibrated for ≤1.0 dB inter-channel gain variation and ≤3.0° phase mismatch.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 77 GHz radar receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BGT77L22 | Single-channel 76–81 GHz RX with integrated PLL; no on-chip VGA or baseband filters; requires external IF conditioning. | Best suited for cost-sensitive SRR where channel count and integration level are lower priority than footprint. | Select when system uses external gain control and filtering, and only one RX channel per module is required. |
| TI AWR2944RQF | Monolithic 76–81 GHz SoC integrating MCU, ADC, DSP, and dual RX channels; higher integration but fixed architecture. | Targets full radar ECU replacement rather than modular front-end expansion; not interoperable with MR2001V/T chipset. | Select when consolidating radar processing onto a single die is preferred over scalable multi-chip architecture. |
Compared with Infineon BGT77L22 and TI AWR2944RQF, MC33MR2001R2VKR2 offers superior channel scalability (3 independent RX), on-die baseband filtering, and seamless compatibility with NXP's MR2001V/MR2001T transceiver family-enabling flexible LRR/MRR/SRR platform reuse without redesign.

FAQ
What is the RF input frequency range supported by the MC33MR2001R2VKR2?
The MC33MR2001R2VKR2 supports an RF input frequency range of 76 GHz to 77 GHz, aligned with the globally harmonized W-band allocation for automotive radar. This range enables compliance with ETSI EN 302 264 and FCC Part 95 regulations for long-, mid-, and short-range radar applications. The device maintains specified conversion gain, noise figure, and linearity across the full 76–77 GHz band at temperatures from −40 °C to +125 °C.
How does the MC33MR2001R2VKR2 interface with the Qorivva MPC577xK MCU?
The MC33MR2001R2VKR2 interfaces with the Qorivva MPC577xK MCU via a 10 MHz SPI bus (SEB/MOSI/MISO/SCLK) and shares timing-critical signals including the 38 GHz LO input. Its baseband output characteristics-including 5 MHz IF bandwidth, 300 kHz high-pass filter edge, and differential DC-coupled outputs-are co-designed with the MPC577xK's ADC input specs. The MCU handles system calibration, chirp generation, and FFT processing while directly reading sensor data (temperature, saturation) from the MC33MR2001R2VKR2.
Does the MC33MR2001R2VKR2 include on-chip gain control, and how is it configured?
Yes, the MC33MR2001R2VKR2 includes two cascaded variable-gain amplifier (VGA) stages providing 20–61 dB total conversion gain in 5.5 dB steps. Gain is configured exclusively via SPI register writes-no external analog control voltage is required. Each channel's gain is independently adjustable, and gain settings persist across sleep/wake cycles. The device also supports automatic gain control (AGC) logic implemented in the host MCU using saturation detector (SD) and sensor (SENS) feedback from the MC33MR2001R2VKR2.
What package type and mounting specifications apply to the MC33MR2001R2VKR2?
The MC33MR2001R2VKR2 uses a 6.0 × 6.0 × 0.95 mm RCPBGA package with a 10 × 11 solder ball array and 0.5 mm pitch. It requires PCB-level RF grounding per NXP's layout guidelines, including dedicated GND1 (RF ground) and GND (DC ground) vias, controlled-impedance 50 Ω traces for RX/LO lines, and tight decoupling (three 100 nF + one 1 μF) per VCC domain (VCC1/VCC2/VCC3). Reflow profile follows JEDEC J-STD-020D for moisture sensitivity level 3.
Can the MC33MR2001R2VKR2 be used without the MR2001V VCO and MR2001T transmitter?
Yes, the MC33MR2001R2VKR2 can operate with third-party 38 GHz LO sources and separate 77 GHz transmitters, provided they meet its electrical interface requirements: −11 to 0 dBm single-ended LO power, 50 Ω matched RF inputs, and timing-aligned SPI control. However, full system-level calibration, baseband filter alignment, and thermal compensation are optimized when used with the complete MR2001 chipset (MR2001V + MR2001T + MC33MR2001R2VKR2), especially with the Qorivva MPC577xK MCU.
