Product details
Overview
HMC340ALP5ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced dual mixer IC operating from 1.7 to 4.5 GHz RF/LO and DC–1.5 GHz IF, delivering 8.0 dB typical conversion loss, +20 dBm input IP3, and 45 dB LO/RF isolation. It serves as an upconverter, downconverter, or I/Q modulator in wireless infrastructure transceivers.
For engineers reviewing the HMC340ALP5ETR datasheet, HMC340ALP5ETR pinout, HMC340ALP5ETR application, or HMC340ALP5ETR equivalent, key selection criteria include its dual-channel symmetry for image-reject architectures, 5×5 mm QFN package with exposed ground paddle, and passive diode-based topology requiring no bias current.
Technical Context
The HMC340ALP5ETR integrates two identical double-balanced mixer cores on a single GaAs die, each using Schottky diodes and monolithic baluns to achieve broadband RF/LO matching and high port-to-port isolation. Its symmetrical architecture enables precise amplitude and phase balance (0.1 dB gain balance) critical for SSB and I/Q modulation.
It operates passively with +13 dBm LO drive, exhibits DC-coupled RF and LO ports (50 Ω matched), and requires external DC blocking only on IF when DC operation is not needed. Thermal resistance is 60.4 °C/W junction-to-package base, supporting operation from –40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.7–4.5 GHz - supports full-band wireless infrastructure band planning (e.g., 2.3–2.7 GHz LTE, 3.4–3.8 GHz 5G) |
| IF Frequency Range | DC–1.5 GHz - enables baseband I/Q generation and low-IF receiver designs without AC coupling constraints |
| Conversion Loss | 8.0 dB typ. - defines signal path attenuation; impacts cascaded noise figure and required LO drive level |
| Input IP3 | +20 dBm - determines third-order intermodulation headroom in multi-carrier systems like WLL base stations |
| LO/RF Isolation | 45 dB typ. - suppresses LO leakage into antenna paths, easing filter requirements in TDD/FDD front-ends |
| Amplitude Balance | 0.1 dB max. - ensures <0.5° phase error in I/Q modulators, critical for EVM compliance in 256-QAM systems |
| Package | 32-lead 5×5 mm QFN (LP5) with exposed ground paddle - requires soldered thermal pad for 1.07 W power dissipation at 85 °C |
Pinout & Package
32-lead RoHS-compliant 5×5 mm QFN package (LP5E) with exposed ground paddle; all ground leads and paddle must be soldered to PCB RF ground per Hittite land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 7–11, 13–18, 20, 21, 23–28, 30–32 | N/C | No connection; may be tied to RF ground without performance impact |
| 3, 6 | LO1, LO2 | DC-coupled 50 Ω LO inputs - accept +13 dBm drive; require no external bias or blocking |
| 12, 29 | IF2, IF1 | DC-coupled IF outputs - support DC operation up to 4 mA sink/source; otherwise require series AC-coupling capacitor |
| 19, 22 | RF2, RF1 | DC-coupled 50 Ω RF ports - enable direct connection to PA/LNA stages without DC blocking |
| Bottom Pad | GND | Thermal and RF ground - must be fully soldered to PCB ground plane for thermal management and isolation integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LC5 | Wider RF/LO range (1.5–6.0 GHz), higher conversion loss (9.5 dB), same LP5 package | Better suited for 5–6 GHz 5G FR1 bands but trades off ~1.5 dB NF | Select when extending coverage beyond 4.5 GHz; verify LO drive tolerance (+15 dBm max) |
| ADL5802ACPZ-R7 | Single balanced dual mixer, 700 MHz–2.8 GHz, integrated LO buffer, +17 dBm IP3 | Requires external LO amplification; lower IP3 limits multi-carrier linearity | Choose for lower-frequency sub-3 GHz systems needing active LO drive and smaller footprint |
Compared with HMC340ALP5ETR, HMC1048LC5 extends frequency coverage at the cost of conversion loss, while ADL5802ACPZ-R7 offers integrated LO buffering below 2.8 GHz but sacrifices IP3 and upper-band capability - making HMC340ALP5ETR optimal for 3–4 GHz 5G infrastructure where linearity and balance are critical.

FAQ
What is the recommended LO drive level for optimal performance of the HMC340ALP5ETR?
The HMC340ALP5ETR achieves best conversion loss (8.0 dB), IP3 (+20 dBm), and isolation with +13 dBm LO drive. Performance degrades below +11 dBm (increased conversion loss) or above +15 dBm (risk of compression). The device supports LO drive up to +27 dBm absolute maximum, but +13 dBm is the design center for datasheet specifications.
Can the HMC340ALP5ETR operate with DC-coupled IF outputs in a zero-IF receiver?
Yes - the HMC340ALP5ETR IF ports (pins 12 and 29) are DC-coupled and support true DC–1.5 GHz operation. However, the device must not source or sink more than ±4 mA per IF port to avoid die damage. External DC-blocking capacitors are only required if DC operation is not needed.
Is the HMC340ALP5ETR pin-compatible with the HMC340ALP5 variant?
Yes - HMC340ALP5ETR and HMC340ALP5 share identical 32-lead 5×5 mm QFN (LP5) footprints, pin functions, and electrical specifications. The "E" suffix denotes RoHS-compliant matte tin plating (vs. Sn/Pb), with identical MSL1 rating and 260 °C peak reflow tolerance.
How does the HMC340ALP5ETR achieve image rejection without external hybrids?
The HMC340ALP5ETR itself does not provide image rejection alone - it requires external 90° hybrids and combiners to form an image-reject mixer (IRM) or I/Q modulator. Its dual-mixer symmetry (0.1 dB amplitude/phase match) ensures minimal imbalance-induced image residual when implemented in such architectures.
What thermal management is required for continuous operation of the HMC340ALP5ETR at full RF power?
The HMC340ALP5ETR has a thermal resistance of 60.4 °C/W (junction-to-package base). To maintain junction temperature ≤125 °C at 85 °C ambient and 1.07 W dissipation, the PCB must provide low-thermal-resistance grounding: the exposed paddle must be fully soldered to a solid copper ground plane with ≥6 thermal vias (0.3 mm diameter) connecting to inner/secondary ground layers.
