Product details
Overview
HMC377QS16GETR from Analog Devices (formerly Hittite Microwave) is a monolithic GaAs MMIC downconverter IC designed for cellular infrastructure receivers operating in the 0.8–1.0 GHz RF band. It integrates a high-linearity passive mixer and IF amplifier, delivering +15 dBm input IP3, 14 dB conversion gain, and 11 dB single-sideband noise figure at 70 MHz IF, with only –5 dBm LO drive and +5 V/135 mA supply - enabling compact, high-dynamic-range base station front-ends.
For engineers reviewing the HMC377QS16GETR datasheet, HMC377QS16GETR pinout, HMC377QS16GETR application, or HMC377QS16GETR equivalent, key selection criteria include its cellular-band RF frequency range (0.8–1.0 GHz), IF bandwidth support (50–250 MHz), absence of external baluns, and compatibility with GSM/CDMA/GPRS/EDGE infrastructure signal chains requiring high IP3 and low-noise downconversion.
Technical Context
The HMC377QS16GETR implements a double-balanced passive mixer core followed by a broadband IF amplifier stage, all on a single GaAs die. Its architecture eliminates need for external baluns by integrating on-chip RF and LO port matching to 50 Ω across 0.8–1.0 GHz, while supporting tunable IF output from 50 MHz to 250 MHz via external LC network adjustment.
LO-to-RF isolation exceeds 23 dB, LO-to-IF isolation reaches 70 dB, and RF-to-IF isolation achieves 90 dB - critical for suppressing LO leakage and image interference in dense multi-carrier cellular base stations. The device operates over –40°C to +85°C and requires no DC blocking on RF or LO ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

FAQ
What is the RF frequency range supported by the HMC377QS16GETR?
The HMC377QS16GETR supports an RF input frequency range of 0.8–1.0 GHz, optimized for GSM and CDMA cellular uplink bands. This range is verified per datasheet specifications at TA = +25°C with LO = –5 dBm and Vdd = +5 V. Operation outside this band degrades conversion gain and isolation performance, and is not characterized or guaranteed.
Does the HMC377QS16GETR require external baluns for RF or LO inputs?
No, the HMC377QS16GETR does not require external baluns. Its RF and LO ports are internally matched to 50 Ω across the full 0.8–1.0 GHz band, as confirmed in the functional diagram and application circuit. Only a 100 pF AC-coupling capacitor is needed on the LO input (Pin 2), and no balun or transformer is specified in the recommended layout.
What is the recommended IF frequency range and how is tuning implemented for the HMC377QS16GETR?
The HMC377QS16GETR supports IF output frequencies from 50 MHz to 250 MHz. Tuning is achieved via external LC matching network on Pin 10 (IF Output), with documented capacitor values for 70 MHz (150 pF), 120 MHz (56 pF), 170 MHz (27 pF), and 247 MHz (12 pF). Matching must be optimized per target IF per application note AN-1073.
What are the absolute maximum ratings for supply voltage and RF input power on the HMC377QS16GETR?
The HMC377QS16GETR has an absolute maximum Vdd rating of +7 Vdc and a maximum RF input power of +13 dBm. Exceeding these limits risks permanent damage. Recommended operating conditions specify +4.5 V to +5.5 V for Vdd and ≤+10 dBm RF input to maintain linearity and avoid compression. Thermal derating begins above +85°C ambient.
Is the HMC377QS16GETR pin-compatible with the HMC420QS16GETR?
No, the HMC377QS16GETR is not pin-compatible with the HMC420QS16GETR. Although both use the QSOP-16 package, their pin functions differ: HMC420QS16GETR assigns Pin 8 to Vdd_IF and Pin 10 to IF_OUT, whereas HMC377QS16GETR uses Pin 8 for IF_Bias and Pin 10 for IF_OUT with distinct biasing requirements. Layout redesign is required for substitution.
