Product details
Overview
HMC304MS8E from Hittite Microwave Corporation is a GaAs MMIC passive single-balanced mixer in an 8-lead MSOP package, operating from 1.7–3.0 GHz RF/LO and DC–0.8 GHz IF, delivering +30 dBm typical input IP3, 9–10.5 dB conversion loss, and 20–30 dB LO-to-RF isolation for high-dynamic-range downconversion in PCS, 3G, and 2.4 GHz ISM systems.
For engineers reviewing the HMC304MS8E datasheet, HMC304MS8E pinout, HMC304MS8E application, or HMC304MS8E equivalent, key selection criteria include its no-external-components operation, RoHS-compliant matte Sn lead finish, MSL1 rating with 260 °C peak reflow, and guaranteed performance across –40 °C to +85 °C.
Technical Context
The HMC304MS8E integrates GaAs Schottky diodes and on-chip planar transformer baluns to achieve true single-balanced operation without external matching components. Its RF port is balanced via the internal balun while the LO connects directly to the diode quad, enabling high LO-to-RF isolation (20–30 dB) and low conversion loss (9–10.5 dB) at +17 dBm LO drive.
Designed for downconversion (with upconversion yielding ~5 dB lower IP3), it supports broadband IF bandwidth (DC–800 MHz) and exhibits stable P1dB (18–19.5 dBm) and IP3 (27–32 dBm) over temperature and frequency, verified at 2 GHz RF and 100 MHz IF under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.7–3.0 GHz - fully specified operational band for RF and LO ports, enabling use in PCS (1.85–1.99 GHz) and 3G (2.11–2.17 GHz) bands. |
| IF Frequency Range | DC–0.8 GHz - supports baseband and low-IF architectures including zero-IF receivers and wideband IF sampling. |
| Input IP3 (Typ.) | +30 dBm - enables handling of strong interferers in dense spectral environments without compression or intermodulation distortion. |
| Conversion Loss (Typ.) | 9–10.5 dB - defines signal attenuation through mixing path; impacts system noise figure and gain budget planning. |
| LO-to-RF Isolation (Typ.) | 30 dB - reduces LO leakage into antenna or front-end, easing filtering requirements and improving receiver blocking immunity. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial and outdoor wireless infrastructure applications without derating. |
| Package | 8-lead MSOP (14.8 mm²) - surface-mount footprint compatible with automated assembly; requires all ground leads soldered to PCB RF ground. |
Pinout & Package
Package: 8-lead MSOP (Mini Small Outline Package), RoHS-compliant low-stress injection-molded plastic body with 100% matte tin lead finish, MSL1 rated (260 °C peak reflow), outline per Hittite drawing 9-163.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF+ (Balanced) | Positive terminal of balanced RF input; must be terminated in 50 Ω differential or single-ended via external balun if required. |
| 2 | GND | RF ground connection; must be soldered directly to PCB ground plane with multiple vias. |
| 3 | LO | Single-ended LO input; accepts +13 to +19 dBm drive; no DC blocking required. |
| 4 | GND | LO ground; electrically isolated from RF ground in layout but tied to common ground at system level. |
| 5 | GND | IF ground; shared reference for IF output path. |
| 6 | IF | Single-ended IF output; delivers converted signal with DC–800 MHz bandwidth; AC-coupled in most implementations. |
| 7 | GND | Additional ground lead; mandatory soldering ensures thermal and RF stability. |
| 8 | RF– (Balanced) | Negative terminal of balanced RF input; completes differential RF interface; requires matched trace length to Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | On-die baluns and diode quad eliminate need for external transformers, capacitors, or bias tees-reducing BOM count and board area. |
| +30 dBm typical input IP3 | Enables robust operation in spectrally crowded environments such as cellular base stations and point-to-point radios without front-end attenuation. |
| Ultra-small MSOP8 footprint (14.8 mm²) | Minimizes PCB real estate in space-constrained modules like small-cell radios and portable test equipment. |
| RoHS-compliant matte Sn finish | Supports lead-free manufacturing with 260 °C peak reflow tolerance and eliminates Pb-based solder compatibility concerns. |
| –40 °C to +85 °C operating range | Validated performance across full industrial temperature range without gain or linearity degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive single-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (1.5–4.0 GHz), higher conversion loss (11.5 dB typ.), same MSOP8 package and RoHS finish. | Better suited for 3.5 GHz WiMAX or 4 GHz point-to-point links where HMC304MS8E's 3.0 GHz upper limit is insufficient. | Select HMC1048LP3E when extending beyond 3.0 GHz is required; expect ~2 dB higher conversion loss and reduced IP3 at upper band edge. |
| QH304MS8 | Same pinout and electrical specs, but manufactured by Qorvo (post-Hittite acquisition); identical marking "H304" and MSL1 rating. | No functional or layout change needed; drop-in replacement for continuity after Hittite brand transition. | Choose QH304MS8 for long-term supply assurance and identical second-source availability without redesign. |
Compared with HMC1048LP3E and QH304MS8, the HMC304MS8E offers optimal balance of IP3, conversion loss, and size for 1.7–3.0 GHz applications-making it preferred for PCS, 3G, and 2.4 GHz ISM where bandwidth and linearity are tightly coupled.

FAQ
What is the maximum LO drive level supported by the HMC304MS8E?
The HMC304MS8E supports a maximum LO drive level of +27 dBm, with optimal performance achieved at +17 dBm. Operating above +19 dBm may increase distortion without meaningful conversion gain improvement, and absolute maximum rating must not be exceeded to avoid permanent damage. The HMC304MS8E datasheet specifies +17 dBm as the standard test condition for IP3 and conversion loss.
Does the HMC304MS8E require external DC bias or matching components?
No, the HMC304MS8E requires no external DC bias or matching components due to its integrated GaAs Schottky diode quad and on-chip planar transformer baluns. All ports operate passively: LO is driven single-ended, RF is balanced, and IF is single-ended. This eliminates bias networks, DC blocks, and external baluns-simplifying layout and reducing bill-of-materials cost for the HMC304MS8E.
What is the difference between HMC304MS8 and HMC304MS8E?
The HMC304MS8 uses Sn/Pb lead finish and has a 235 °C max peak reflow temperature, while the HMC304MS8E is RoHS-compliant with 100% matte Sn finish and a 260 °C reflow rating. Both share identical electrical specifications, pinout, package dimensions, and marking "H304". The HMC304MS8E is the lead-free version intended for modern SMT processes.
Can the HMC304MS8E be used for upconversion?
Yes, the HMC304MS8E can be used for upconversion, though with ~5 dB lower input IP3 compared to downconversion mode. The datasheet confirms similar performance in both directions, with the primary specification table explicitly noting that upconversion yields an input IP3 approximately 5 dB less than the downconverter value. System-level verification at the target IF and RF frequencies is recommended for HMC304MS8E upconverter designs.
What PCB layout practices are critical for optimal HMC304MS8E performance?
Optimal HMC304MS8E performance requires grounding all eight package leads-especially Pins 2, 4, 5, and 7-to a solid RF ground plane using multiple vias; maintaining 50 Ω controlled impedance on RF and IF traces; and avoiding stubs or discontinuities near the balanced RF ports (Pins 1 and 8). The HMC304MS8E evaluation board (102643) uses Rogers 4350 substrate and serves as a validated reference layout.
