Product details
Overview
HMC470ATCPZ-EP-PT 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 total attenuation range, and ±0.3 dB typical state error at 2.3–3.0 GHz. It delivers high linearity (P0.1dB = 27 dBm @ 5 V), low insertion loss (1.7 dB typ. @ 2.3–3.0 GHz), and military-grade thermal operation (−55°C to +125°C), deployed in microwave radios and VSAT RF front-ends.
For engineers reviewing the HMC470ATCPZ-EP-PT datasheet, HMC470ATCPZ-EP-PT pinout, HMC470ATCPZ-EP-PT application, or HMC470ATCPZ-EP-PT equivalent, key selection criteria include its 16-lead 3 mm × 3 mm LFCSP package, CMOS/TTL-compatible parallel control interface (V1–V5), ACGx capacitor pins for sub-700 MHz extension, and enhanced product qualification per AQEC standards for defense/aerospace use.
Technical Context
The HMC470ATCPZ-EP-PT implements a monolithic GaAs-based 5-bit DSA architecture with binary-weighted attenuation states (0–31 dB in 1 dB steps), where each bit (V1–V5) controls discrete 1/2/4/8/16 dB segments. Its RF path is dc-coupled to VDD and ac-matched to 50 Ω on both RF1 and RF2 ports, requiring external dc blocking capacitors.
It integrates on-chip CMOS/TTL level-shifting drivers for parallel control and six ACGx pins (ACG1–ACG6) enabling external ac grounding capacitors to extend low-frequency operation below 700 MHz-critical for IF and broadband test equipment applications requiring stable attenuation down to 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.1 GHz to 3.0 GHz - supports cellular infrastructure, microwave radio, and VSAT bands without external tuning. |
| Attenuation Range & Step | 31 dB total range in 1 dB LSB steps - enables precise RF power leveling across 32 discrete states for closed-loop control systems. |
| Insertion Loss | 1.7 dB typical @ 2.3–3.0 GHz - minimizes signal degradation in high-frequency transmit/receive chains. |
| P0.1dB | 27 dBm @ VDD = 5 V - sustains high-power RF signals without compression in radar and point-to-point links. |
| Phase Shift | 27° max @ 1.5–3.0 GHz - ensures minimal phase distortion during attenuation switching in coherent systems. |
| Supply Voltage | 3 V to 5 V single supply - simplifies biasing in mixed-signal boards with shared 3.3 V or 5 V rails. |

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-RL7 | Same die, identical specs, but supplied in 7-inch tape-and-reel (RL7) vs. tray (PT); MSL3 rating and AQEC compliance unchanged. | No functional difference; RL7 preferred for high-volume SMT assembly, PT for prototyping and small-batch evaluation. | Select HMC470ATCPZ-EP-RL7 for production runs requiring automated placement; retain HMC470ATCPZ-EP-PT for lab validation and design-in. |
| Qorvo QM11036 | 5-bit GaAs DSA with 31 dB range, but 0.5 dB LSB, 2.5 dB insertion loss @ 2.5 GHz, and commercial temp range (−40°C to +85°C). | Lacks military temperature rating and AQEC qualification; suitable only for commercial infrastructure or test gear not requiring extended thermal margin. | Choose QM11036 only if cost sensitivity outweighs reliability requirements and operation stays within −40°C to +85°C. |
Compared with HMC470ATCPZ-EP-RL7, the HMC470ATCPZ-EP-PT offers identical RF performance and qualification but differs in packaging format-making it optimal for engineering validation. Against QM11036, the HMC470ATCPZ-EP-PT provides superior temperature resilience, lower insertion loss, and tighter attenuation accuracy essential for defense and aerospace deployments.

FAQ
What is the operating temperature range of the HMC470ATCPZ-EP-PT?
The HMC470ATCPZ-EP-PT is qualified for continuous operation from −55°C to +125°C, meeting AQEC standards for defense and aerospace applications. This extended range is verified per MIL-STD-883 methods and supported by thermal resistance data (θJC = 130°C/W) and power derating curves up to 125°C case temperature. The HMC470ATCPZ-EP-PT maintains specified insertion loss, attenuation accuracy, and P0.1dB performance across this full range.
Does the HMC470ATCPZ-EP-PT require external dc blocking capacitors?
Yes, the HMC470ATCPZ-EP-PT requires external dc blocking capacitors on both RF1 and RF2 pins because its RF path is dc-coupled to VDD. Capacitor value must be selected based on the lowest operating frequency - for example, ≥100 pF for 100 MHz operation. The HMC470ATCPZ-EP-PT datasheet specifies this requirement in the Pin Function Descriptions and Figure 5 interface schematic.
How does the ACGx pin configuration affect low-frequency performance of the HMC470ATCPZ-EP-PT?
The ACGx pins (ACG1–ACG6) on the HMC470ATCPZ-EP-PT enable operation below 700 MHz when connected to external capacitors ≥100 pF. Without these capacitors, performance degrades below 700 MHz; with them, the HMC470ATCPZ-EP-PT maintains specified attenuation accuracy and return loss down to 0.1 GHz. This capability is explicitly validated in the datasheet's General Description and Pin Function Descriptions.
Is the HMC470ATCPZ-EP-PT pin-compatible with the commercial-grade HMC470A?
No - the HMC470ATCPZ-EP-PT shares the same pinout and footprint as the commercial HMC470A, but it is not guaranteed as a drop-in replacement due to differences in qualification, screening, and thermal derating. While mechanical and electrical pin mapping matches, the HMC470ATCPZ-EP-PT undergoes additional AQEC-level testing and has distinct absolute maximum ratings (e.g., higher RF input power limit at elevated temperatures). System validation is required before substitution.
What is the maximum RF input power the HMC470ATCPZ-EP-PT can handle at 125°C case temperature?
At TCASE = 125°C, the HMC470ATCPZ-EP-PT supports a maximum continuous RF input power of 27 dBm when VDD = 5 V, as specified in the Absolute Maximum Ratings table. This value is derived from its 0.19 W maximum power dissipation limit at 125°C and confirmed by Figure 3 (Power Dissipation vs. Case Temperature). The HMC470ATCPZ-EP-PT maintains this rating across all attenuation states in the 250 MHz to 3 GHz band.
