Product details
Overview
ADRF6601ACPZ-R7 from Analog Devices is a high-dynamic-range active RF mixer with integrated fractional-N PLL and VCO, operating as a receiver front-end component in cellular base station signal chains. It supports 300 MHz to 2500 MHz RF input, 750–1160 MHz internal LO generation, 6.7 dB voltage conversion gain, 31 dBm input IP3 (typ.), and 500 MHz IF bandwidth - enabling direct-conversion or low-IF architectures for LTE and WCDMA infrastructure.
For engineers reviewing the ADRF6601ACPZ-R7 datasheet, ADRF6601ACPZ-R7 pinout, ADRF6601ACPZ-R7 application, or ADRF6601ACPZ-R7 equivalent, key selection criteria include its integrated synthesizer performance (−222 dBc/Hz figure of merit), programmable IIP3 via IP3SET pin, matched 200 Ω differential IF output, SPI-controlled configuration, and 40-lead 6 mm × 6 mm LFCSP package with exposed paddle thermal management.
Technical Context
The ADRF6601ACPZ-R7 implements a silicon-germanium BiCMOS architecture with a fully integrated fractional-N PLL using a sigma-delta modulator (modulus 1–2047) and a 2× fLO VCO followed by ÷2/÷4 dividers. Its charge pump current is programmable (250/500/750/1000 µA), and VTUNE range is 1.5–2.5 V, supporting external loop filter design for phase noise optimization.
It features dual-mode LO operation: internal synthesis (PLL_EN = high) or external 1× LO injection (PLL_EN = low), with LOP/LON pins configurable as inputs or outputs via LODRV_EN and register control. The mixer core delivers 14.5 dBm P1dB and supports high-side LO injection with <1.2 dB gain variation over −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Range | 300–2500 MHz ±3 dB; enables single device coverage across GSM, UMTS, LTE bands without external switching. |
| Internal LO Range | 750–1160 MHz; supports high-side injection for 3G/4G uplink/downlink conversion with minimal image rejection complexity. |
| IIP3 (typ.) | 31 dBm at 910 MHz; ensures robust linearity against strong adjacent-channel interferers in dense cellular environments. |
| Noise Figure | 13.3–14.8 dB (IP3SET = 3.3 V); balances low-noise amplification and intermodulation suppression for high-sensitivity receivers. |
| Voltage Conversion Gain | 6.7 dB into 200 Ω differential load; simplifies interface to baseband ADCs or analog filters without external gain stages. |
| IF Bandwidth | 500 MHz small-signal 3 dB BW; supports wide instantaneous bandwidth for multi-carrier and OFDMA signal processing. |
| Supply Current | 294 mA (internal LO mode, IP3SET = 3.3 V); defines power budget for active mixer + synthesizer integration in compact RRUs. |
Pinout & Package
ADRF6601ACPZ-R7 uses a 40-lead, 6 mm × 6 mm LFCSP package with exposed paddle (EPAD) soldered to ground for thermal and electrical integrity. Pin count and layout match the ADRF660x family footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFIN | Single-ended RF input | 50 Ω impedance; requires external matching network for optimal return loss across 300–2500 MHz band. |
| IFP / IFN | Differential IF output | 200 Ω matched impedance; requires external RF chokes to VCC for common-mode biasing and swing control. |
| LOP / LON | LO input/output pair | Configurable as 1× LO source (internal VCO) or sink (external LO); supports high-isolation switching via PLL_EN/LODRV_EN logic. |
| IP3SET | IIP3 optimization control | Open or pulled to 3.3 V to select between 13.5 dB (open) and 14.6 dB (3.3 V) SSB noise figure; enables trade-off tuning. |
| VTUNE | VCO tuning voltage input | Accepts 1.5–2.5 V from external loop filter; sets LO frequency with <10 mV/°C drift over temperature. |
| REF_IN | Reference clock input | 12–160 MHz ac-coupled; drives PFD with 4 dBm typical level; supports crystal oscillator or clock generator sources. |
| CLK/DATA/LE | SPI serial interface | 24-bit register access at ≤20 MHz clock; LE edge-triggered latch enables deterministic configuration timing per Table 5. |
Key Features
| Feature | Design Value |
|---|---|
| Fractional-N PLL with Σ-Δ modulator | Enables fine LO step resolution (<1 Hz) and flexible channel spacing without requiring large integer dividers or multiple VCO banks. |
| Programmable charge pump current | Four selectable levels (250–1000 µA) allow loop filter optimization for phase noise vs. lock time trade-offs in different deployment scenarios. |
| Integrated 200 Ω IF output termination | Eliminates need for external resistive matching networks, reducing board area and preserving signal integrity up to 500 MHz. |
| Temperature-stable gain flatness | 0.2 dB over any 5 MHz span and 1.2 dB total variation across −40°C to +85°C ensures consistent dynamic range in outdoor macro cells. |
| RoHS-compliant LFCSP package | 6 mm × 6 mm footprint with exposed paddle provides <35°C/W θJA, enabling conduction-cooled designs in space-constrained remote radio units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer with integrated synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADRF6602ACPZ-R7 | Wider internal LO range (1550–2150 MHz); higher RF input range (1000–3100 MHz); same 40-lead LFCSP package. | Targeted at TDD-LTE and WiMAX bands above 2 GHz; not suitable for sub-1 GHz cellular uplink paths. | Select ADRF6602ACPZ-R7 only when LO >1550 MHz is required; pinout-compatible but register map differs in PLL divider settings. |
| ADRF6702ACPZ-R7 | Includes integrated VGA (−15 to +15 dB gain); no integrated PLL/VCO; requires external synthesizer; 40-lead LFCSP. | Used where variable gain control is critical and LO path is centralized; lacks on-chip frequency synthesis capability. | Choose ADRF6702ACPZ-R7 when system-level LO distribution is preferred and gain agility outweighs integration benefits. |
Compared with ADRF6602ACPZ-R7 and ADRF6702ACPZ-R7, the ADRF6601ACPZ-R7 uniquely combines sub-1 GHz RF coverage, integrated fractional-N PLL, and optimized noise-linearity trade-off for legacy and emerging cellular infrastructure - making it the only option supporting 300–2500 MHz with on-chip LO generation in this package.

FAQ
What is the RF input frequency range supported by the ADRF6601ACPZ-R7?
The ADRF6601ACPZ-R7 supports an RF input frequency range of 300 MHz to 2500 MHz (±3 dB). This range covers major cellular bands including GSM 850/900, UMTS 2100, LTE Bands 1–3, 7, 8, 20, and 40. Performance is characterized at 610 MHz, 910 MHz, and 1020 MHz with input return loss, P1dB, IP3, and noise figure specified across temperature.
Does the ADRF6601ACPZ-R7 require external loop filter components?
Yes, the ADRF6601ACPZ-R7 requires an external third-order loop filter connected between CP (Pin 3) and VTUNE (Pin 39). The charge pump output drives the filter to generate the VCO tuning voltage. Filter design depends on selected charge pump current (250–1000 µA), desired loop bandwidth, and phase margin - Analog Devices provides reference schematics in the evaluation board documentation.
How is the IIP3 performance adjusted on the ADRF6601ACPZ-R7?
The ADRF6601ACPZ-R7 allows IIP3 optimization via the IP3SET pin (Pin 29): leaving it open yields 13.5 dB SSB noise figure and ~31 dBm IIP3, while pulling it to 3.3 V improves noise figure to 14.6 dB and increases IIP3 by ~1–2 dB depending on frequency and temperature. No external resistor is needed - the pin senses voltage level directly.
Can the ADRF6601ACPZ-R7 operate with an external LO instead of the internal PLL?
Yes, the ADRF6601ACPZ-R7 supports external 1× LO injection via LOP/LON pins (Pins 38/37) when PLL_EN (Pin 16) is set low. In this mode, the internal PLL and VCO are powered down, reducing supply current to 184 mA. The external LO must be 750–1160 MHz, −6 to +6 dBm, and 50 Ω terminated.
What is the recommended power supply decoupling for the ADRF6601ACPZ-R7?
Each power supply pin (VCC1, VCC2, VCC_LO, VCC_MIX, VCC_V2I) requires local decoupling with a 100 pF capacitor in parallel with a 0.1 µF capacitor placed as close as possible to the pin. Dedicated decoupling nodes DECL3P3 (Pin 2), DECL2P5 (Pin 9), and DECLVCO (Pin 40) must each connect to ground via a 0.1 µF capacitor (DECLVCO also requires a 10 µF bulk capacitor).
