Product details
Overview
HMC423MS8ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer IC with integrated LO amplifier, operating from 0.6 GHz to 1.3 GHz as upconverter or downconverter. It delivers 8 dB typical conversion loss, +15 dBm input IP3 at 1.3 GHz, and requires only 0 dBm LO drive and +3 V/15 mA supply - ideal for compact RF front-ends in portable wireless infrastructure.
For engineers reviewing the HMC423MS8ETR datasheet, HMC423MS8ETR pinout, HMC423MS8ETR application, or HMC423MS8ETR equivalent, key selection criteria include its integrated LO amplifier enabling low-drive operation, DC-coupled RF/IF ports, 50 Ω matched RF/LO interfaces, and MSL1 RoHS-compliant 8-lead MSOP package compatibility with standard SMT reflow profiles.
Technical Context
This monolithic microwave integrated circuit implements a double-balanced Gilbert-cell mixer topology with on-die LO buffer amplifier, enabling single-ended LO drive without external amplification. The design supports both upconversion and downconversion modes with IF bandwidth extending from DC to 400 MHz.
DC-coupled RF and IF ports allow baseband or low-IF architectures, while AC-coupled 50 Ω LO input ensures broadband impedance match across 0.6–1.3 GHz. Thermal design accounts for 320 mW max dissipation at 85 °C with 4.8 mW/°C derating above that temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 0.6–1.3 GHz - supports cellular band I/II/III and ISM 902–928 MHz applications |
| IF Bandwidth | DC–400 MHz - enables zero-IF and low-IF receiver architectures |
| Conversion Loss | 8 dB typ. - defines signal attenuation through mixing path; impacts system noise figure |
| Input IP3 | +15 dBm typ. at 1.3 GHz - determines linearity headroom for two-tone interference rejection |
| LO Drive Level | 0 dBm - eliminates need for external LO buffer stage, reducing BOM and board area |
| Supply | +3 V, 15 mA - enables direct integration into 3.3 V systems with minimal power overhead |
| LO–RF Isolation | 25–35 dB - suppresses LO leakage into antenna path, easing filter requirements |

| 2, 3, 6, 7 | Ground | Must be soldered directly to RF ground plane; critical for isolation and thermal dissipation |
| 4 | Vdd | +3 V supply for integrated LO amplifier; requires 10,000 pF RF bypass capacitor |
| 5 | IF Output/Input | DC-coupled port; supports DC–400 MHz; max ±18 mA DC current to avoid damage |
| 8 | RF Input/Output | DC-coupled 50 Ω port; matched across 0.6–1.3 GHz; handles +13 dBm max RF input |
Key Features

| High LO–RF isolation (35 dB typ.) | Minimizes LO radiation into antenna path, relaxing filtering requirements in transceiver front-ends |
| Wide IF bandwidth (DC–400 MHz) | Supports flexible IF planning including zero-IF, complex IF, and wideband digital predistortion feedback paths |
Applications
| Cellular Base Stations | Portable Wireless Terminals |
|---|---|
Use Scenario: Mid-tier macrocell and small cell transceivers requiring compact, low-power upconversion from baseband to 900 MHz or 1.2 GHz bands. IC Role / Device Role / Timing Role: Double-balanced mixer performing final RF upconversion with integrated LO amplification.

IC Role / Device Role / Timing Role: High-isolation mixer handling simultaneous channel aggregation with minimal LO feedthrough. Use Value: 35 dB LO–RF isolation reduces intermodulation distortion between adjacent channels, supporting DOCSIS 3.1 spectral efficiency targets. | Use Scenario: Industrial telemetry radios operating in 902–928 MHz ISM band requiring robust upconversion with minimal external components. IC Role / Device Role / Timing Role: Low-LO-drive mixer enabling direct interface to low-power fractional-N synthesizers. Use Value: 0 dBm LO drive tolerance allows use of ultra-low-power PLLs, extending battery life in remote sensor nodes without sacrificing +8 dBm P1dB compression point. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC215MS8G | Higher frequency range (2–18 GHz), no integrated LO amplifier, requires +13 dBm LO drive | Designed for microwave backhaul and radar; lacks low-IF support due to 100 MHz min IF | Select when operating above 1.3 GHz or when external LO buffering is already present |
| ADL5801ACPZ-R7 | Wider RF range (10–6000 MHz), higher conversion gain (+4 dB), but higher supply current (45 mA) | Optimized for wideband software-defined radio; includes integrated baluns and bias tees | Select for multi-band SDR platforms where 3 V/15 mA constraint is less critical than bandwidth |
Compared with HMC423MS8ETR, HMC215MS8G trades integrated LO drive for extended frequency coverage, while ADL5801ACPZ-R7 offers broader bandwidth and gain at the cost of higher power - making HMC423MS8ETR optimal for cost- and power-sensitive 0.6–1.3 GHz fixed-band applications.

FAQ
What is the maximum RF input power rating for the HMC423MS8ETR?
The HMC423MS8ETR supports a maximum RF input power of +13 dBm under continuous operation with Vdd = +3 V. Exceeding this level risks permanent degradation of the GaAs die, especially during sustained high-power or high-temperature conditions. Derating is recommended above +85 °C ambient per the 4.8 mW/°C thermal specification.
Does the HMC423MS8ETR require external matching components on the RF or LO ports?
No, the HMC423MS8ETR features internal 50 Ω matching on both the AC-coupled LO port (Pin 1) and DC-coupled RF port (Pin 8) across its full 0.6–1.3 GHz operating range. Only a single 10,000 pF bypass capacitor on Vdd (Pin 4) and proper RF grounding of Pins 2, 3, 6, and 7 are required for functional operation.
Can the HMC423MS8ETR operate with an IF frequency of 0 Hz (DC-coupled baseband)?
Yes, the HMC423MS8ETR supports true DC-coupled IF operation via Pin 5. However, the IF port must not source or sink more than ±18 mA DC current to prevent device malfunction or die failure. For baseband applications, ensure downstream circuitry complies with this current limit and provides appropriate DC biasing.
What is the recommended PCB layout practice for the HMC423MS8ETR ground connections?
All ground pins (2, 3, 6, 7) must be soldered directly to a solid, low-inductance RF ground plane using multiple vias. The outline drawing specifies that mold flash exclusion applies, so solder fillets must fully wet each lead. Avoid daisy-chaining grounds or routing signals near ground leads to preserve LO–RF isolation and thermal performance.
Is the HMC423MS8ETR pin-compatible with the non-RoHS HMC423MS8 variant?
Yes, the HMC423MS8ETR is functionally and mechanically identical to the HMC423MS8, sharing the same 8-lead MSOP footprint, pinout, electrical specifications, and thermal profile. The only differences are RoHS compliance (100% matte Sn finish vs. Sn/Pb) and MSL1 reflow rating (260 °C vs. 235 °C), making it a drop-in replacement in new designs.
