Product details
Overview
HMC306MS10 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC 5-bit digital attenuator in MSOP-10 package, delivering 0.5 dB LSB steps across 15.5 dB range with ±0.2 dB typical bit error, 0.7–3.8 GHz frequency coverage, and +52 dBm IIP3 at Vdd = 5 V - deployed in UMTS/3G infrastructure RF front-ends for precise gain control.
For engineers reviewing the HMC306MS10 datasheet, HMC306MS10 pinout, HMC306MS10 application, or HMC306MS10 equivalent, key selection criteria include broadband insertion loss flatness (1.3–2.3 dB), single positive control per bit (0/+3 to +5 V), RoHS-compliant Sn/Pb lead finish, and MSOP-10 thermal performance up to +85 °C.
Technical Context
The HMC306MS10 implements a monolithic GaAs MMIC architecture with five independent CMOS-compatible control inputs driving discrete attenuation cells. Each bit (0.5/1/2/4/8 dB) operates via voltage-toggled switches with matched path impedance, enabling sum-of-bits attenuation states without interpolation.
It requires only one external bias resistor (5 kΩ) on Vdd (3–5 V), DC-blocking capacitors on RF1/RF2 ports, and operates with no internal voltage regulation - all control logic is level-sensitive (0 V low, Vdd high), with 20 µA max input current per control line.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.7–3.8 GHz - supports full-band operation in UMTS, WiMAX, and VSAT without re-tuning. |
| Attenuation Range & Step | 0.5–15.5 dB in 0.5 dB LSB increments - enables fine-grained RF power leveling in closed-loop AGC systems. |
| Insertion Loss | 1.3–2.3 dB (typ.) across band - minimizes signal degradation in cascaded RF chains before LNA or mixer stages. |
| IIP3 | +52 dBm at 5 V - ensures high linearity for multi-tone signals in base station transceivers. |
| Bit Accuracy | ±0.2 dB typical absolute bit error - guarantees predictable attenuation state matching in calibration-critical test equipment. |
| Switching Speed | 600 ns tON/tOFF - supports dynamic channel switching in TDD-based wireless protocols. |
| Operating Temp. | −40 to +85 °C - validated for industrial and outdoor telecom equipment deployment. |
Pinout & Package
Package: MSOP-10 (3.0 × 3.0 × 1.1 mm, 15 mm² footprint), low-stress injection-molded plastic, Sn/Pb lead finish, MSL1 rated, with all ground leads (Pins 1, 2, 9, 10) requiring direct PCB ground plane connection per RF design best practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, Pin 2, Pin 9, Pin 10 | Ground | RF and DC return paths - must be soldered directly to solid ground plane with multiple vias. |
| Pin 3 | RF1 Input | Primary RF signal entry port - requires DC-blocking capacitor (100–300 pF). |
| Pin 4 | RF2 Output | Attenuated RF output port - requires DC-blocking capacitor (100–300 pF). |
| Pin 5 | Vdd Bias | +3 to +5 V supply input - connected via external 5 kΩ resistor; powers all attenuation cells. |
| Pin 6 | V1 (8 dB) | Positive control for 8 dB bit - high = enabled, low = bypassed; CMOS-compatible (0 / Vdd). |
| Pin 7 | V2 (4 dB) | Positive control for 4 dB bit - independent toggle; same voltage interface as V1. |
| Pin 8 | V3 (2 dB) | Positive control for 2 dB bit - enables granular attenuation combinations with V1–V5. |
Key Features
| Feature | Design Value |
|---|---|
| 0.5 dB LSB resolution | Enables precise RF power adjustment in 0.5 dB increments across full 15.5 dB range for calibration-grade instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5-bit digital attenuator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC624LP4E | 4-bit, 31 dB range, 0.5–8 GHz, +47 dBm IIP3, QFN-24 package | Higher frequency coverage but lower resolution and wider bandwidth trade-off | Select when >4 GHz operation required and 1 dB LSB suffices |
| PE43703 | 6-bit, 31.5 dB range, 9 kHz–6 GHz, +44 dBm IIP3, QFN-24 package | Wider frequency range and higher resolution but lower linearity and larger footprint | Select for wideband lab instrumentation needing sub-0.25 dB steps below 1 GHz |
Compared with HMC306MS10, HMC624LP4E offers extended bandwidth but sacrifices 1 bit of resolution and 5 dB IIP3 headroom, while PE43703 provides finer resolution and ultra-low-frequency support at the cost of reduced linearity and increased board area - HMC306MS10 remains optimal for 0.7–3.8 GHz telecom infrastructure demanding tight bit accuracy and high OIP3.

FAQ
What is the operating frequency range of the HMC306MS10?
The HMC306MS10 operates from 0.7 GHz to 3.8 GHz with specified insertion loss, return loss, and attenuation accuracy across this band. Performance is characterized at +25 °C with Vdd = +3 V to +5 V, and the device maintains functional operation across its full rated temperature range of −40 to +85 °C within this frequency span.
Does the HMC306MS10 require external DC-blocking capacitors?
Yes, the HMC306MS10 requires external DC-blocking capacitors on both RF1 (Pin 3) and RF2 (Pin 4) ports. The datasheet specifies 100–300 pF values selected based on the lowest operational frequency to minimize insertion loss while ensuring DC isolation - omission causes RF shorting and potential damage.
What is the control interface voltage requirement for the HMC306MS10?
The HMC306MS10 uses five positive-only control inputs (V1–V5, Pins 6–8 and two additional pins) toggled between 0 V (low) and Vdd (high), where Vdd is +3 V to +5 V. Each control line draws ≤20 µA, and logic thresholds are defined as 0 to +0.2 V (low) and Vdd ± 0.2 V (high); no negative or differential signaling is supported.
Is the HMC306MS10 pin-compatible with the HMC306MS10E?
Yes, the HMC306MS10 and HMC306MS10E share identical pinout, electrical specifications, and MSOP-10 package dimensions. The sole difference is RoHS compliance: HMC306MS10E uses 100% matte tin lead finish and 260 °C peak reflow, while HMC306MS10 uses Sn/Pb and 235 °C peak reflow - both are drop-in replacements in compatible assembly processes.
What is the maximum RF input power the HMC306MS10 can handle?
The HMC306MS10 has an absolute maximum RF input power rating of +28 dBm across 0.7–3.8 GHz. Under normal operation at Vdd = +5 V, the 0.1 dB compression point is +25 dBm; at Vdd = +3 V, it drops to +23 dBm. Exceeding these levels risks permanent parametric shift or failure.
