Product details
Overview
ADSC584WCBCZ4A12 from Analog Devices is an obsolete GaAs-based voltage-controlled oscillator (VCO) designed for microwave signal generation, operating from 12.2 GHz to 13.9 GHz at RFOUT and 6.1 GHz to 6.95 GHz at RFOUT/2, with -110 dBc/Hz phase noise at 100 kHz offset, +1 dBm RFOUT output power, and 250 mA typical current consumption - used in phased-array radar and satellite uplink transmitters.
For engineers reviewing the ADSC584WCBCZ4A12 datasheet, ADSC584WCBCZ4A12 pinout, ADSC584WCBCZ4A12 application, or ADSC584WCBCZ4A12 equivalent, key selection considerations include tuning voltage range (2 V to 18 V), dual-output frequency coverage, phase noise performance, output power distribution between fundamental and divided outputs, and LFCSP-32 package thermal and RF layout constraints.
Technical Context
The ADSC584WCBCZ4A12 integrates a monolithic GaAs VCO core with integrated buffer amplifiers and a divide-by-2 circuit, enabling simultaneous fundamental and half-frequency outputs. Its wide 2 V–18 V tuning voltage range supports coarse and fine frequency adjustment across the full 12.2–13.9 GHz band without band-switching.
Phase noise is optimized via low-noise biasing and on-die resonator design, achieving -110 dBc/Hz at 100 kHz offset. Output power asymmetry (+1 dBm at RFOUT, +7 dBm at RFOUT/2) reflects internal gain staging and division loss compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RFOUT) | 12.2 GHz to 13.9 GHz - covers X-band upper edge through Ku-band lower edge for radar and comms. |
| Frequency Range (RFOUT/2) | 6.1 GHz to 6.95 GHz - enables local oscillator derivation for downconversion without external dividers. |
| Phase Noise | -110 dBc/Hz @ 100 kHz offset - meets stringent spectral purity requirements for coherent radar systems. |
| Output Power (RFOUT) | +1 dBm - sufficient to drive active mixers or further amplification stages in compact front ends. |
| Output Power (RFOUT/2) | +7 dBm - higher than fundamental output due to internal gain compensation after division. |
| Tuning Voltage Range | 2 V to 18 V - supports wide-range PLL loop design with standard charge-pump voltages and filtering. |
| Supply Current | 250 mA typical - defines thermal load and PCB copper area requirements in high-density RF modules. |
Pinout & Package
ADSC584WCBCZ4A12 is housed in a 32-lead, 5 mm × 5 mm LFCSP package with exposed paddle for thermal dissipation and RF grounding. Pin assignments are defined per Analog Devices ADF5584 datasheet Rev. A (2019), with dedicated RFOUT, RFOUT/2, VTUNE, VCC, GND, and NC terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 7–10, 13–16, 19–22, 25–28, 31–32 | GND | RF and power ground connections requiring low-inductance PCB vias to internal paddle. |
| 5, 11, 17, 23, 29 | VCC | 5 V supply inputs - each must be decoupled locally with 100 nF + 10 pF near the pin. |
| 6 | RFOUT | Fundamental RF output port, matched to 50 Ω, requires microstrip launch with minimal discontinuity. |
| 12 | RFOUT/2 | Divided output port, +7 dBm, DC-blocked internally - suitable for direct LO injection. |
| 18 | VTUNE | Analog tuning voltage input (2–18 V); sensitive to noise - requires RC filtering and guard ring. |
| 24 | NC | No-connect terminal - must remain unconnected and floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output architecture | Simultaneous 12.2–13.9 GHz and 6.1–6.95 GHz outputs eliminate need for external frequency dividers in LO chains. |
| Wide tuning voltage range | 2 V to 18 V enables use with standard PLL charge pumps and simplifies loop filter design for broadband locking. |
| Integrated buffer amplifiers | Isolates VCO core from load variations, ensuring stable oscillation and consistent phase noise under varying POUT conditions. |
| Low-phase-noise GaAs process | Monolithic GaAs implementation delivers -110 dBc/Hz @ 100 kHz, critical for coherent detection in pulsed radar. |
| LFCSP thermal management | 5 mm × 5 mm exposed-pad package supports >1.5 W thermal dissipation with proper PCB copper pour and via array. |
Applications
| Radar Transmitter LO Source | Satellite Uplink Local Oscillator |
|---|---|

Use Value: +1 dBm RFOUT provides adequate drive level for downstream calibration-grade amplifiers without added noise figure penalty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC586LC4B | Single-output (12.5–14.5 GHz), no internal divider; -112 dBc/Hz @ 100 kHz; 200 mA supply current. | Requires external divider for half-frequency LO; better phase noise but narrower tuning range. | Select when highest spectral purity is prioritized over dual-output convenience. |
| ADF5508 | Obsolete Analog Devices part; same LFCSP-32 package; 11.5–13.2 GHz range; -109 dBc/Hz @ 100 kHz; +2 dBm RFOUT. | Lower frequency coverage; slightly higher output power; identical pinout and biasing. | Consider only for legacy redesigns where footprint compatibility is mandatory. |
Compared with HMC586LC4B and ADF5508, ADSC584WCBCZ4A12 uniquely delivers simultaneous fundamental and divided outputs in a single GaAs die, trading 2 dB phase noise margin for integrated functionality that reduces external component count and layout complexity in multi-LO systems.

FAQ
Is ADSC584WCBCZ4A12 still in production?
No, ADSC584WCBCZ4A12 is marked obsolete by Analog Devices and not released to production. It remains available through authorized distributors and Aetrix Electronics' legacy component program with full traceability and extended lifecycle support for existing designs.
What is the recommended power supply configuration for ADSC584WCBCZ4A12?
ADSC584WCBCZ4A12 requires a clean, well-decoupled 5 V supply applied to five VCC pins (pins 5, 11, 17, 23, 29). Each pin must be bypassed with a 100 nF ceramic capacitor and a 10 pF RF capacitor placed within 1 mm of the pin to suppress supply-induced phase noise and ensure stable oscillation.
Can ADSC584WCBCZ4A12 be used without an external loop filter?
No - ADSC5584WCBCZ4A12 is a VCO only and requires an external PLL IC (e.g., ADF41513) and loop filter to achieve closed-loop frequency control. The VTUNE pin (pin 18) expects analog tuning voltage from the PLL's charge pump output, not direct DC bias.
Does ADSC584WCBCZ4A12 require external matching networks at RFOUT?
No - ADSC584WCBCZ4A12 features internally matched 50 Ω output impedance at RFOUT (pin 6). A simple 50 Ω microstrip launch with minimal discontinuity is sufficient; no external matching components are needed for nominal operation.
How does the RFOUT/2 output differ electrically from RFOUT on ADSC584WCBCZ4A12?
The RFOUT/2 output (pin 12) delivers +7 dBm across 6.1–6.95 GHz with DC blocking integrated on-die, while RFOUT (pin 6) delivers +1 dBm across 12.2–13.9 GHz and is AC-coupled externally. RFOUT/2 exhibits lower phase noise than expected from ideal division due to internal gain compensation and buffering.
