Product details
Overview
HMC470ATCPZ-EP-RL7 from Analog Devices is a 5-bit GaAs digital step attenuator (DSA) operating from 0.1 GHz to 3.0 GHz with 1 dB LSB resolution, 31 dB attenuation range, and ±0.3 dB accuracy. It delivers 27 dBm P0.1dB at 5 V supply and supports military-grade operation from −55°C to +125°C in cellular infrastructure and microwave radio RF front-ends.
For engineers reviewing the HMC470ATCPZ-EP-RL7 datasheet, HMC470ATCPZ-EP-RL7 pinout, HMC470ATCPZ-EP-RL7 application, or HMC470ATCPZ-EP-RL7 equivalent, key selection criteria include attenuation linearity below 1 GHz, ACGx capacitor interface for sub-700 MHz extension, LFCSP thermal performance, and CMOS/TTL parallel control compatibility.
Technical Context
The HMC470ATCPZ-EP-RL7 implements a monolithic GaAs-based 5-bit DSA architecture with on-chip driver enabling direct CMOS/TTL parallel control across V1–V5 pins. Its RF path uses dc-coupled 50 Ω matching at RF1/RF2, requiring external dc blocking capacitors and optional ACGx ac-grounding caps for operation below 700 MHz.
It features enhanced product qualification per AQEC standards: single fabrication/assembly/test site, controlled manufacturing baseline, and extended temperature operation (−55°C to +125°C). Thermal design relies on exposed pad grounding, with θJC = 130°C/W and θJA = 297°C/W on JEDEC 2S2P board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.1 GHz to 3.0 GHz - fully characterized RF attenuation performance across cellular, microwave, and VSAT bands. |
| Attenuation Range & Step | 31 dB total range in 1 dB LSB steps - enables precise RF gain control without interpolation or calibration. |
| Insertion Loss | 1.7 dB typical at 2.3–3.0 GHz - low signal loss preserves system noise figure and dynamic range. |
| P0.1dB | 27 dBm typical at VDD = 5 V - supports high-power RF stages without compression in base station transceivers. |
| Phase Shift | 27° max between min/max attenuation states at 1.5–3.0 GHz - minimizes phase distortion in coherent IF/RF paths. |
| Supply Voltage | 3 V to 5 V single supply - simplifies biasing and enables interoperability with common logic rails. |
| Control Interface | CMOS-/TTL-compatible parallel inputs (V1–V5) - eliminates need for level shifters in FPGA/microcontroller-driven systems. |
Pinout & Package
Package: 16-lead, 3 mm × 3 mm LFCSP (CP-16-51), exposed pad must be grounded for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply input | Single 3–5 V rail powering internal GaAs core and on-chip driver; requires local decoupling. |
| RF1 (Pin 2), RF2 (Pin 11) | RF I/O ports | DC-coupled, 50 Ω matched ports; require external DC blocking capacitors sized for lowest operating frequency. |
| V1–V5 (Pins 12–16) | Digital control inputs | Parallel 5-bit word selecting attenuation state (0–31 dB); TTL/CMOS logic thresholds defined per spec. |
| ACG1–ACG6 (Pins 4–9) | AC grounding terminals | Connect ≥100 pF capacitors only for operation <700 MHz; leave open above 700 MHz. |
| NIC (Pins 3, 10) | No internal connection | Not bonded; measured data assumes connection to RF/DC ground on evaluation board. |
| Exposed Pad | Thermal & electrical ground | Mandatory solder connection to PCB ground plane for junction cooling and RF return path integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced Product Qualification | AQEC-compliant with −55°C to +125°C operation, single fab/test site, and controlled baseline - meets defense/aerospace sourcing requirements. |
| Sub-700 MHz Extension | ACGx pins support external capacitors to maintain attenuation accuracy down to 0.1 GHz - avoids redesign when extending band coverage. |
| High Linearity | IP3 = 50 dBm and P0.1dB = 27 dBm at 5 V - sustains signal integrity in multi-tone LTE/5G transmit chains. |
| Low Phase Distortion | 27° max relative phase shift over full attenuation range at 1.5–3.0 GHz - critical for phased array and IQ modulation stability. |
| Compact Thermal Package | 3 mm × 3 mm LFCSP with exposed pad achieves θJC = 130°C/W - enables high-density RF module integration without forced air. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital step attenuator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC470ATCPZ-EP-PT | Same die, identical specs, but supplied in tape-and-reel vs. cut-tape; RoHS compliant; same CP-16-51 package and Y6U marking. | Identical functional use; differs only in packaging format - PT is full reel, RL7 is 7-inch reel. | Select HMC470ATCPZ-EP-PT for high-volume automated assembly; choose HMC470ATCPZ-EP-RL7 for prototyping or medium-batch SMT lines. |
| Qorvo QM11024 | 5-bit DSA, 0.05–6.0 GHz, 31 dB range, but uses serial SPI interface and has higher insertion loss (2.5 dB typ @ 3 GHz) and lower P0.1dB (24 dBm). | Better ultra-wideband coverage but lacks parallel control and military temp rating; not AQEC qualified. | Choose QM11024 only if SPI interface and >3 GHz coverage are mandatory; otherwise HMC470ATCPZ-EP-RL7 offers superior linearity, phase stability, and defense-grade reliability. |
Compared with HMC470ATCPZ-EP-PT and QM11024, the HMC470ATCPZ-EP-RL7 uniquely combines parallel CMOS control, −55°C to +125°C operation, and 27 dBm linearity in a thermally optimized LFCSP - making it the preferred choice for ruggedized, high-performance RF systems where timing determinism and environmental resilience are critical.

FAQ
What is the operating temperature range of the HMC470ATCPZ-EP-RL7?
The HMC470ATCPZ-EP-RL7 is qualified for continuous operation from −55°C to +125°C, meeting AQEC standards for defense and aerospace applications. This extended range is verified across all electrical parameters including insertion loss, attenuation accuracy, and P0.1dB, with full characterization at −55°C, +25°C, +85°C, and +125°C per the datasheet's typical performance plots.
Does the HMC470ATCPZ-EP-RL7 require external dc blocking capacitors?
Yes, the HMC470ATCPZ-EP-RL7 requires external dc blocking capacitors on both RF1 and RF2 pins because its RF ports are dc-coupled to VDD. Capacitor value must be selected based on the lowest operating frequency - for example, ≥100 pF for 0.1 GHz operation - and placed as close as possible to the pins to maintain impedance match and minimize parasitic inductance.
How does the ACGx pin configuration affect low-frequency performance of the HMC470ATCPZ-EP-RL7?
The ACGx pins (ACG1–ACG6) allow the HMC470ATCPZ-EP-RL7 to extend accurate attenuation operation down to 0.1 GHz when ≥100 pF capacitors are connected. Above 700 MHz, these pins must remain unconnected to avoid degrading RF performance. This configurable interface provides design flexibility without requiring separate part numbers for different frequency bands.
Is the HMC470ATCPZ-EP-RL7 pin-compatible with the commercial-grade HMC470A?
No - the HMC470ATCPZ-EP-RL7 is not pin-compatible with the commercial HMC470A. While both share the same 16-lead LFCSP footprint, the EP version includes additional ACGx pins (Pins 4–9) repurposed for ac grounding, whereas the commercial variant uses those pins differently or leaves them unused. Layout reuse is not supported without verification against respective pin function tables.
What is the maximum RF input power the HMC470ATCPZ-EP-RL7 can handle continuously?
The HMC470ATCPZ-EP-RL7 supports continuous RF input power up to 27 dBm at VDD = 5 V and TCASE = 85°C, with derating required above that temperature. At TCASE = 125°C, maximum continuous dissipation drops to 0.19 W per absolute maximum ratings. Power handling is validated across all attenuation states and frequencies from 250 MHz to 3.0 GHz.
