Product details
Overview
HMC273MS10GE from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC 5-bit digital attenuator in MSOP-10 package, providing 1–16 dB LSB steps across 0.7–3.8 GHz with ≤2.5 dB typical insertion loss, ±0.2 dB typical bit error, and +48 dBm IIP3 at 5 V. It serves as a precision RF signal level control element in cellular infrastructure and microwave radio front-ends.
For engineers reviewing the HMC273MS10GE datasheet, HMC273MS10GE pinout, HMC273MS10GE application, or HMC273MS10GE equivalent, key selection criteria include broadband attenuation accuracy, GaAs-based high-linearity performance, MSOP-10 thermal and RF layout requirements, and single-supply 3–5 V positive-control logic compatibility.
Technical Context
The HMC273MS10GE implements a monolithic GaAs MMIC architecture with five independent CMOS-compatible control inputs (V1–V5), each toggling between 0 V and Vdd to select 1/2/4/8/16 dB attenuation bits. Bias is supplied via a single 3–5 V rail through an external 5 kΩ resistor to Pin 6 or Pin 10.
It operates over –40 °C to +85 °C with 150 °C channel temperature limit and requires DC-blocking capacitors on RF1/RF2 ports. Return loss exceeds 10 dB across full band, and switching times are 560 ns (tRISE/tFALL) and 600 ns (tON/tOFF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.7–3.8 GHz: supports UMTS, WiMAX, VSAT, and test equipment bands without re-tuning. |
| Attenuation Range | 0–31 dB in 1 dB LSB steps: enables precise RF gain control for closed-loop AGC systems. |
| Insertion Loss | ≤2.5 dB typical (0.7–1.4 GHz): minimizes signal path degradation in cascaded RF stages. |
| IIP3 | +48 dBm at 5 V: ensures high linearity for multi-tone signals in base station transceivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital RF attenuator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC624LP4E | 6-bit, 0.1–8 GHz, 0.5 dB LSB, higher insertion loss (3.5 dB typ), QFN-24 package | Wider bandwidth but lower resolution and larger footprint; requires more PCB area and decoupling. | Select when extended frequency coverage beyond 3.8 GHz or finer 0.5 dB steps are required. |
| PE43711 | 5-bit, 9 kHz–6 GHz, 1 dB LSB, 3.3 V only, 24-lead QFN, integrated SPI interface | Includes serial control and wider LF coverage but lacks GaAs linearity (+42 dBm IIP3 vs. +48 dBm). | Select when SPI bus integration and sub-GHz operation are mandatory, accepting reduced high-power linearity. |
Compared with HMC273MS10GE, HMC624LP4E offers broader bandwidth but sacrifices resolution and compactness, while PE43711 adds digital interface convenience at the cost of GaAs-level linearity and thermal efficiency in high-power RF stages.

FAQ
What is the operating frequency range of the HMC273MS10GE?
The HMC273MS10GE operates from 0.7 GHz to 3.8 GHz. Within this band, insertion loss remains ≤2.5 dB (typical at 0.7–1.4 GHz), return loss exceeds 10 dB, and attenuation accuracy holds within ±0.2 dB typical. Performance is specified across the full range with validated data for 0.7–1.4 GHz, 1.4–2.3 GHz, 2.3–2.7 GHz, 2.7–3.7 GHz, and 3.7–3.8 GHz sub-bands.
Does the HMC273MS10GE require external DC-blocking capacitors?
Yes, the HMC273MS10GE requires external DC-blocking capacitors on both RF1 and RF2 ports. The datasheet specifies C1 = C2 = 100–300 pF to pass the lowest operational frequency with minimal loss. These capacitors isolate DC bias from the RF signal path and are mandatory for proper functionality in AC-coupled RF designs.
What supply voltage range is supported by the HMC273MS10GE?
The HMC273MS10GE supports a single positive supply voltage (Vdd) from +3 V to +5 V, with ±0.2 V tolerance. An external 5 kΩ resistor must be used to connect Vdd to either Pin 6 or Pin 10. Control inputs (V1–V5) toggle between 0 V (low) and Vdd (high), making it compatible with standard 3.3 V or 5 V logic families.
Is the HMC273MS10GE pin-compatible with the HMC273MS10G?
Yes, the HMC273MS10GE is pin-compatible with the HMC273MS10G. Both share identical MSOP-10 pinout, electrical specifications, and functional behavior. The 'E' suffix denotes RoHS-compliant packaging (100% matte Sn lead finish, MSL1, 260 °C peak reflow), whereas the non-E version uses Sn/Pb finish and 235 °C reflow.
What is the maximum RF input power rating for the HMC273MS10GE?
The HMC273MS10GE has an absolute maximum RF input power rating of +30 dBm across 0.7–3.7 GHz. Under normal operation at Vdd = 5 V, the input power for 0.1 dB compression is +27 dBm; at Vdd = 3 V, it is +22 dBm. Exceeding these levels risks permanent damage or parametric shift due to channel temperature exceeding 150 °C.
