Product details
Overview
HMC380QS16GE from Analog Devices (formerly Hittite Microwave) is a high-linearity passive mixer-based RF downconverter IC designed for PCS/UMTS infrastructure receivers operating from 1.7–2.2 GHz RF, with 50–300 MHz IF output and -5 dBm LO drive requirement. It delivers +19 dBm input IP3, 11.5 dB conversion gain, and 9 dB SSB noise figure on a single +5 V supply drawing 165 mA - enabling robust signal reception in base station front-ends.
For engineers reviewing the HMC380QS16GE datasheet, HMC380QS16GE pinout, HMC380QS16GE application, or HMC380QS16GE equivalent, key selection criteria include its high IP3 performance at low LO drive, integrated IF amplifier, absence of external baluns, and MSL1 RoHS-compliant 16-lead QSOP package optimized for 1.7–2.2 GHz cellular infrastructure downconversion.
Technical Context
The HMC380QS16GE implements a passive double-balanced mixer core followed by a high-dynamic-range IF amplifier, supporting low-side LO injection and delivering broadband RF-to-IF conversion without external baluns. Its architecture achieves high linearity via optimized passive mixing and IF gain staging, with all RF/IF ports internally matched to 50 Ω over specified bands.
It operates across -40°C to +85°C with absolute maximum ratings including +13 dBm RF input, +15 dBm LO drive, and +7 Vdc supply voltage. Thermal resistance is 59 °C/W (channel-to-ground paddle), and the exposed ground slug requires direct PCB grounding for RF and thermal performance.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP4E | Wider RF range (1.7–4.2 GHz), higher +22 dBm IIP3, but requires -10 dBm LO drive and consumes 220 mA | Better suited for multi-band LTE-A base stations needing extended frequency coverage | Select when broader RF bandwidth and higher linearity outweigh LO drive and power constraints |
| LT5560EFE#TRPBF | Lower +15 dBm IIP3, 5.5 dB conversion gain, 12.5 dB NF, but operates from 0.1–3 GHz and uses +3.3 V supply | Targeted at portable and low-power small-cell applications where size and voltage compatibility matter | Select when system-level power budget is tighter and moderate linearity suffices |

FAQ
What is the RF frequency range supported by the HMC380QS16GE?
The HMC380QS16GE supports an RF input frequency range of 1.7–2.2 GHz, fully characterized for PCS and UMTS infrastructure applications. This range covers key cellular bands including UMTS Band I (2100 MHz), PCS Band (1900 MHz), and extended PHS/CDMA allocations. Performance metrics such as conversion gain, noise figure, and IP3 are guaranteed across this span under standard test conditions (TA = +25°C, LO = -5 dBm, Vdd = 5 V).
Does the HMC380QS16GE require external baluns for operation?
No, the HMC380QS16GE does not require external baluns. Its internal passive double-balanced mixer architecture and 50 Ω matched RF/LO ports eliminate the need for discrete baluns. This simplifies PCB layout, reduces component count, and improves repeatability in high-volume manufacturing - a key advantage confirmed in the device's functional description and application circuit documentation.
What is the recommended LO drive level for optimal performance of the HMC380QS16GE?
The HMC380QS16GE is optimized for a typical LO drive level of -5 dBm, with a specified range of -5 to 0 dBm. Operating within this range ensures maximum conversion gain (11.5 dB), lowest noise figure (9 dB), and highest input IP3 (+19 dBm). Deviating below -5 dBm degrades linearity and gain; exceeding 0 dBm risks reliability due to absolute maximum LO rating of +15 dBm.
Can the HMC380QS16GE be used with IF frequencies other than 250 MHz?
Yes, the HMC380QS16GE supports IF frequencies from 50 MHz to 300 MHz. While 250 MHz is the default test condition, the device has been validated at 70 MHz using external tuning components (L2 and C6 per application circuit). Matching networks must be adjusted per target IF frequency to maintain optimal conversion gain and noise performance - guidance for tuning is provided in the datasheet's application section.
What thermal management considerations apply to the HMC380QS16GE?
The HMC380QS16GE features an exposed ground paddle with a thermal resistance of 59 °C/W (channel-to-ground). To ensure reliable operation at full rated power (1.10 W continuous at TA = 85°C), all ground pins (11, 12, 13) and the backside paddle must be soldered directly to a low-impedance RF/DC ground plane using multiple thermal vias. Failure to do so may cause junction temperature exceedance and parametric drift or failure.
